Description

BACKGROUND

Modern communications rely on antennas to communicate wireless signals between devices. A transmitting antenna can broadcast a signal around itself without regard to direction and a receiving antenna can receive the signal. However, using an antenna that is not focused on a specific location can be less effective in some instances and have a less desired outcome.

SUMMARY

In one embodiment, a system can comprise a first log-periodic antenna panel with a first geometry and a second log-periodic antenna panel with a second geometry. The first log-periodic antenna panel and the second log-periodic antenna panel can be arranged along about the same plane next to one another. The first geometry and the second geometry can be different in orientation.

In another embodiment, a system can comprise a first log-periodic antenna panel with a first geometry and a second log-periodic antenna panel with a second geometry. In addition, the system can comprise a first ground plate coupled to the first log-periodic antenna panel that causes the first log-periodic antenna panel to be more directional and a second ground plate coupled to the second log-periodic antenna panel that causes the second log-periodic antenna panel to be more directional. The system can also comprise a first feed coupled to the first log-periodic antenna panel and a second feed coupled to the second log-periodic antenna panel. The system can additionally comprise a management component configured to manage the first feed to be at a normalized 0 degrees and to manage the second feed to be at a 180 degree offset from the first feed. The first log-periodic antenna panel and the second log-periodic antenna panel can be arranged along about the same plane next to one another, with the first geometry and the second geometry do not matching in orientation.

In yet another embodiment, a system can comprise a first log-periodic antenna panel with a first geometry and a second log-periodic antenna panel with a second geometry. In addition, the system can comprise a first ground plate coupled to the first log-periodic antenna panel that causes the first log-periodic antenna panel to be more directional and a second ground plate coupled to the second log-periodic antenna panel that causes the second log-periodic antenna panel to be more directional.

DETAILED DESCRIPTION

Antenna panels (as the antenna radiation elements) can be designed with a mirrored approach and be made of a desired metallic material (e.g., a conducting material), such as copper. The mirrored approach can have the physical geometry such that the panels are a mirror of one another. The panels can operate out of phase of one another, such as 180 degrees out of phase. This can cause an antenna directivity improvement, hence a gain increasing to a higher value.

FIG. 1A illustrates one embodiment of a system 100A comprising a first log-periodic antenna panel 110A and a second log-periodic antenna panel 120A. FIG. 1B illustrates one embodiment of a system 100B comprising a first log-periodic antenna panel with a first geometry 110B and a second log-periodic antenna panel with a second geometry 120B backed by a common ground plate 130. FIG. 1C illustrates one embodiment of an antenna panel 100C (e.g., the first log-periodic antenna panel 110A featuring the first geometry 110B) with a first arm 140A, a second arm 140B, a third arm 140C, and a fourth arm 140D.

The first log-periodic antenna panel 110A and the second log-periodic antenna panel 110B can be arranged along about the same plane next to one another. While being arranged along about the same plane, the second geometry 120B can be a mirror of the first geometry 110B.

In one example, as illustrated in the system 100B, the first geometry 110B and the second geometry 120B can have circular footprints. The first geometry 110B can be implemented as the antenna panel 100C with the four arms 140A, 140B, 140C, and 140D. The first geometry 110B can be split into four hemispheres, such as 0°-90° (first quadrant), 90°-180° (second quadrant), 180°-270° (third quadrant), and 270°-360°/0° (fourth quadrant). The first and second quadrants can form a first hemisphere and the third and fourth quadrants can form a second hemisphere.

The first geometry 110B can have the first arm 140A in the first quadrant extending beyond normalized 45 degrees (e.g., beyond 60 degrees), the second arm 140B in the second quadrant extending beyond normalized 45 degrees, the third arm 140C in the third quadrant extending beyond normalized 45 degrees, and the fourth arm 140D in the fourth quadrant extending beyond normalized 45 degrees. The hemispheres and quadrants can be configured to not overlap, making them separate and distinct.

FIG. 2 illustrates one embodiment of a system 200 comprising the first log-periodic antenna panel 110, the second log-periodic antenna panel 120, a first ground plate 210, a second ground plate 220, a management component 230, a first feed 240, and a second feed 250. The first ground plate 210 and second ground plate 220 can form the common ground plate 130.

The first ground plate 210 can be coupled to the first log-periodic antenna panel 110A that causes the first log-periodic antenna panel 110A to be more directional. The second ground plate 220 can be coupled to the second log-periodic antenna panel 120A that causes the second log-periodic antenna panel 120A to be more directional. An isolated panel can have some aspect of directionality, so the ground plates 210 and 220 can cause the panels 110A and 120A to be more directional than absent the plates 210 and 220. In one example, the first ground plate 210 and the second ground plate 220 can be singular metal sheet. This sheet can stop radiation of the panels 110A and 120A in the direction of the metal sheet so a signal does not travel in that direction past the metal sheet.

The signal can be produced through excitement of the panels 110A and 120A. This excitement can occur through the first feed 240 coupled to the first log-periodic antenna panel 110A and the second feed 250 coupled to the second log-periodic antenna panel 120A.

The management component 230 can be configured to manage the first feed 240 to be at a normalized 0° and to manage the second feed 250 to be at a 180° offset from the first feed. In having the feeds offset and the mirrored geometry, the undesired cross-polarization gain can be down to the minimum value on the boresight direction.

FIG. 3 illustrates one embodiment of a system 300 comprising the first log-periodic antenna panel 110, the second log-periodic antenna panel 120, the first ground plate 210, the second ground plate 220, and a wall 310. The wall 310 can be situated between the antenna panels 110A-120A and the ground plates 210-220 to form a cavity. The wall 310 can cause the cavity to be enclosed or partially open. The wall 310 can provide structural support to hold the panels 110A-120A at a distance from the ground plates 210-220. The wall 310 can be made of a non-metallic material to provide mechanical support or be made of a metallic material to provide mechanical support and improve functionality (e.g., improved boresight gain and/or less radiation on transverse and backside).

FIG. 4 illustrates one embodiment of a system 400 comprising the first log-periodic antenna panel 110, the second log-periodic antenna panel 120, a third log-periodic antenna panel 410, and a fourth log-periodic antenna panel 420. While two panels 110A and 120A are illustrated in FIG. 1, other configurations can be practiced.

In one example, the third log-periodic antenna panel 410 can be employed, such as with the first geometry or a third geometry. In another example, the fourth log-periodic antenna panel 420 can be employed along with the third log-periodic antenna panel 410. The fourth log-periodic antenna panel 420 can be configured with various geometries, such as the second geometry or a fourth geometry. The four panels 110A-120A and 410-420 can be along the same plane, such as the third panel 410 and fourth panel 420 being next to one another and the second panel 120A and third panel 410 being next to one another.

While four panels are illustrated, other configurations can be employed. In one example, three panels can be employed: two with one geometry and one with a different geometry. Other aspects disclosed herein can be precited with a non-two pane configuration, such as three panels forming a cavity or the management component 250 managing excitement of four panels (e.g., two at 0° and two at 180° or one at 0°, one at 90°, one at 180°, and one at 270°).

FIG. 5A illustrates one embodiment of a straight feed 510 and a bent feed 520. FIG. 5B illustrates one embodiment of a perspective view 530 of the first antenna panel 110A with the bent feed 520 (reference numbers 110A and 520 not illustrated in photo in view of difficult reference access to the bent feed 520).

The straight feed 510 and the bent feed 520 can be different implementations of the feeds 240 and 250. For example, the first feed 240 can connect to the first log-periodic antenna panel 110A at a first angle of about 90 degrees and the second feed 250 can connect to the second log-periodic antenna panel 120A at a second angle of about 90 degrees (e.g., the first angle and the second angle are the same angle or different angles).

FIG. 6 illustrates one embodiment of an antenna profile view 600. Two planes are illustrated: a first plane 610 and a second plane 620. The panels 110A and 120A can align along the first plane and the ground plates 210 and 220 can align along the second plane 620. Additionally, a feed plane 630 allows the feeds 240 and 250 to be aligned, such as bent feeds 520.

FIG. 7 illustrates one embodiment of a system 700 comprising a processor 710 (e.g., a general purpose processor, a processor specifically designed for performing a functionality disclosed herein, etc.) and a computer-readable medium 720 (e.g., non-transitory computer-readable medium). In one embodiment, the computer-readable medium 720 is communicatively coupled to the processor 710 and stores a command set executable by the processor 710 to facilitate operation of at least one component disclosed herein (e.g., the management component 230). In one embodiment, at least one component disclosed herein (e.g., the management component 230) can be implemented, at least in part, by way of non-software, such as implemented as hardware by way of the system 700. In one embodiment, the computer-readable medium 720 is configured to store processor-executable instructions that when executed by the processor 710, cause the processor 710 to perform a method disclosed herein (e.g., the method 800 addressed below).

FIG. 8 illustrates one embodiment of a method 800 comprising four actions 810-840. At 810, identification on a broadcast to take place can occur, such as by the management component 250. At 820, a check can occur on if the broadcast should begin at 0° or 180°. If the broadcast should begin at 0°, then the method 800 can employ the first antenna panel 110A at 830; if the broadcast should begin at 180°, then the method 800 can employ the second antenna panel 110A at 840. Actions 830 and 840 can alternate after initial employment.

FIG. 9 illustrates one embodiment of a method 900 comprising four actions 910-940; the method 900 can be a method of manufacture for a system consistent with aspects disclosed herein. At 910, the first log-periodic antenna panel 110A with a first geometry 110B (e.g., with a circular footprint) and the second log-periodic antenna panel 120A with a second geometry 120B (e.g., with a circular footprint mirroring the first geometry 110B) can be placed next to one another along the same plane. At 920, the first ground plate 210 can be coupled to the first log-periodic antenna panel 110A that causes the first log-periodic antenna panel 110A to be directional and the second ground plate 210 can be coupled to the second log-periodic antenna panel 120A that causes the second log-periodic antenna panel 120A to be directional. At 930, the first feed 240 can be coupled to the first log-periodic antenna panel 110A (e.g., at an about 90° angle) and the second feed 240 can be coupled to the second log-periodic antenna panel 120A (e.g., at an about 90° angle). At 940, the wall 310 can be disposed between the antenna panel set (e.g., the first panel 110A and the second panel 120A) and the ground plate set (e.g., the first ground plate 210 and the second ground plate 220) to form the cavity. At 950, the management component 230 can be integrated so that it is configured to manage the first feed 240 to be at a normalized 0° and to manage the second feed 250 to be at a 180° offset from the first feed 240 (e.g., run the method 800).

FIG. 10 illustrates one embodiment of a method 1000 comprising two actions 1010-1020. At 1010, the panels 110A and 120A can be excited by way of the feeds 240 and 250. In response to the excitement, the panels 110A and 120B can radiate directionally at 1020, such as a result of the ground plates 210 and 220.

The panels 110A and 110B and other aspects disclosed herein can be employed in the field of electromagnetics, radio frequency engineering, and antenna deign. This can result in achievement of a wide-frequency band Log-Periodic antenna (e.g., a system comprising the panes 110A and 110B) with high/symmetrical far-field gain patterns using a metallic ground plane (e.g., ground plates 210 and 220) on their back. Aspects disclosed herein can be employed in design wide frequency band antennas using ground plane backed frequency independent antennas, Log-periodic antennas, as well as spiral antennas of varying size, shape, and layering. The wide frequency band Log-Periodic Antenna can be used as an antenna element that is part of an antenna array system or directly used in a large or small antenna array. Aspects disclosed herein can be used to achieve linear vertical polarized (VP), linear horizontal polarized (HP), Right Hand Circularly (RHCP), Polarized, Left Hand Circularly Polarized (LHCP), or a combination of two or more combined polarizations.

Aspects disclosed herein can allow for a wide frequency band log-periodic antenna on a metallic ground plane with a parallel balanced input port (e.g., non 50-ohm) converted to un-balanced 50-ohm (e.g., to be fed to the next level of Radio Frequency (RF) chain or be combined to compose an antenna array) as a single antenna element with a high antenna gain/directivity across the wide frequency band. In addition, feeding can make the antenna array (e.g., with two or more antenna elements, such as the panels 110A and 110B) to achieve high gain/directivity and symmetrical antenna far-field radiation patterns for improved (e.g., maximum) Co-Pol and improved (e.g., minimum or about zero) low level X-Pol.

This can be advantageous in that Log-Periodic antenna configurations with metallic ground plane can have a wide operation frequency band and high antenna gain/directivity. This can be additionally advantageous in that a low side and/or back radiation can be achieved with desirable (e.g., minimum) side and/or back radiation while being conformable. This can be further advantageous in that that it can give desirable (e.g., peak) gain at boresight with VP, HP, RHCP, or/and LHCP polarization.

Frequency independent antennas, such as an antenna built in accordance with aspects disclosed herein, can be antennas whose radiation pattern, RF input impedance and electrical field polarization remain unchanged over a wide frequency bandwidth. There are several configurations that can be employed, such as equiangular, sinuous and Archimedean. A log-periodic antenna panel with a backed ground plane can be used as a wide frequency band antenna and possess high one-side antenna gain/directivity. A log-periodic antenna panel can be used in an array formation in order to increase radiation beam directivity. The log-periodic antenna can be designed with backed ground plane (e.g., the first and second ground plates 210 and 220 as a singular ground plate), balanced-to-unbalanced mode/impedance transformer, and the feeding method of the antenna array which has combined desirable (e.g., maximum) radiation beam on one side with co-polarized (Co-Pol) desirable (e.g., maximum) gain, at least partially canceled cross-polarization (X-Pol), and about symmetrical antenna far-field gain patterns.

The Log-periodic antenna element can be backed with the common ground plate as a flat metallic surface with or without the wall 310 to become a cavity. The cavity can be a common cavity for panels 110A and 120A or have a separator such that two cavities are formed for the individual panels 110A and 120A. This can reduce RF radiation in the transverse direction, hence obtain more radiation energy to the desired front direction antenna gain. Similarly, the ground plate outline profiles can be in different shapes, such as rectangular, circular, etc. and not necessarily match the shape of the antenna panel 110A or 120A.

A balanced-unbalanced mode/impedance transfer board can be the implementation of aspects disclose herein. This board can transfer/convert a balanced mode with about 200˜ 300 ohms impedance to unbalanced microstrip line mode with about 50 ohms.

A very high X-Pol gains (e.g., in the boresight direction which is at 0°) Can result without mirroring the geometries. In employing mirroring, as illustrated by geometries 110B and 120B in reference to one another, very low X-Pol gains (e.g., in the boresight direction which is at 0°) Can be achieved, due to opposite element orientation layout of the two antenna panels 110B and 110A (e.g., antenna elements). In view of the opposite orientated geometries, the 180° phase difference can be employed.

The two-element orientation can be maintained for improved (e.g., maximum) Co-Pol gain to the boresight direction. While mirroring is discussed, other aspects can be practiced. In one example, the second geometry 120B can be laid at a 90° rotation from the first geometry 120A, so the first geometry and the second geometry do not match in orientation yet are not mirrored.

While the methods disclosed herein are shown and described as a series of blocks, it is to be appreciated by one of ordinary skill in the art that the methods are not restricted by the order of the blocks, as some blocks can take place in different orders. Similarly, a block can operate concurrently with at least one other block.
