For facilitating the understanding of the structure of the integrated antenna 100 of the present disclosure, reference is now made to both
As shown in
In this embodiment, lengths of the first antenna 110, the second antenna 120, and the third antenna 130 are different. Therefore, the first antenna 110, the second antenna 120, and the third antenna 130 operate in different frequency bands, for example, the first antenna 110 operates in 2.4 GHz, the second antenna 120 operates in 5 GHz, and the third antenna 130 operates in 6 GHz. In another embodiment, the integrated antenna 100 of the present disclosure can be used in WiFi wireless network with 2.4 GHz and 5 GHz, or can be used in WiFi-7 wireless network with 6 GHz, which operates in 5.95 GHz-7.125 GHz. Since the present disclosure integrates a plurality of antennas to form the integrated antenna 100, the size of antenna can be reduced, so as to decrease overall size of product. In addition, since antennas are integrated into single integrated antenna, there is no need to use different molds to manufacture different types of antennas, thereby reducing the manufacturing cost.
In one embodiment, a first length L1 of the first antenna 110 rangers from 22 millimeters (mm) to 25 millimeters. In another embodiment, the first length L1 of the first antenna 110 can be 22.5 millimeters, 23 millimeters, 23.5 millimeters, 24 millimeters, or 24.5 millimeters.
In one embodiment, a second length L2 of the second antenna 120 rangers from 14 millimeters to 17 millimeters. In another embodiment, the second length L2 of the second antenna 120 can be 14.5 millimeters, 15 millimeters, 15.5 millimeters, 16 millimeters, or 16.5 millimeters.
In one embodiment, a third length L3 of the third antenna 130 rangers from 10 millimeters to 13 millimeters. In another embodiment, the third length L3 of the third antenna 130 can be 10.5 millimeters, 11 millimeters, 11.5 millimeters, 12 millimeters, or 12.5 millimeters. In one embodiment, a width L4 of the third antenna 130 rangers from 5 millimeters to 10 millimeters. In another embodiment, the width L4 of the third antenna 130 can be 6 millimeters, 7 millimeters, 8 millimeters, or 9 millimeters.
In one embodiment, a total length L of the integrated antenna 100 is a sum of the first length L1, the second length L2, and the width L4, and the total length L of the integrated antenna 100 rangers from 40 millimeters to 50 millimeters. In another embodiment, the total length L of the integrated antenna 100 can be 41 millimeters, 42 millimeters, 43 millimeters, 44 millimeters, 45 millimeters, 46 millimeters, 47 millimeters, 48 millimeters, and 49 millimeters.
Reference is now made to
In one embodiment, the first antenna 110 and the second antenna 120 are disposed on a plane. For example, the first antenna 110 and the second antenna 120 are disposed on a XY plane. In addition, the third antenna 130 is perpendicular to the plane. For example, the third antenna 130 is located along Z axis. Therefore, the third antenna 130 is perpendicular to the XY plane.
In one embodiment, feed-in terminals of the first antenna 110, the second antenna 120, and the third antenna 130 are different. For example, a feed-in terminal 111 of the first antenna 110 is located below the first antenna 110 in the figure. A feed-in terminal 121 of the second antenna 120 is located below the second antenna 120 in the figure. A feed-in terminal 131 of the third antenna 130 is located below the third antenna 130 in the figure. In view of the above, the integrated antenna 100 of the embodiment of the present disclosure can be a three-frequency-band and three feed-in antenna. Owing to the first antenna 110, the second antenna 120, and the third antenna 130 having their own feed-in terminal, independent feed-in terminal does not need a multiplexer at a rear end for processing, thereby reducing signal power loss and decreasing the cost of the entire device.
In one embodiment, the first antenna 110, the second antenna 120, and the third antenna 130 share a ground terminal. For example, the first antenna 110, the second antenna 120, and the third antenna 130 may share the ground terminal 140 which is a convergence of the three antennas in the figure. In this embodiment, current paths of the first antenna 110, the second antenna 120, and the third antenna 130 are shown in the figure, and the currents all flow into the ground terminal 140. In another embodiment, the integrated antenna 100 further includes a layer structure 150. The layer structure 150 is disposed on the XZ plane. The first antenna 110, the second antenna 120, and the third antenna 130 are disposed on the layer structure 150.
In one embodiment, the first antenna 110 can be an inverted-F antenna, for example, a Planar Inverted F-shaped Antenna (PIFA). The second antenna 120 can be an inverted-F antenna, and the third antenna 130 can be a ring-shaped antenna. Reference is made to
In one embodiment, the first antenna 110, the second antenna 120, and the third antenna 130 can be all made by metal. For example, the first antenna 110, the second antenna 120, and the third antenna 130 can be made by the same ironwork. Since the integrated antenna 100 can be made by the same ironwork after integrating, there is no need to used different molds to manufacture different ironworks, thereby reducing the manufacturing cost.
It is noted that the present disclosure is not limited to the structure as shown in
As shown in the figure, the first antenna 110A, the second antenna 120A, and the third antenna 130A can be inverted-F antennas. With respect to structures, the inverted-F antenna 110A and the inverted-F antenna 120A can be connected together, and disposed on the XY plane. In addition, the inverted-F antenna 130A is disposed along Z axis, perpendicular to the inverted-F antenna 110A and the inverted-F antenna 120A, and electrically connected to the inverted-F antenna 110A and the inverted-F antenna 120A.
It is noted that the present disclosure is not limited to the structure as shown in
It can be understood from the embodiments of the present disclosure that application of the present disclosure has the following advantages. Since the present disclosure integrates a plurality of antennas to form each of the integrated antennas 100, 100A, the size of each of antennas can be reduced, so as to decrease the overall size of the product. In addition, owing to the first antennas 110, 110A, the second antennas 120, 120A, and the third antennas 130, 130A having their own feed-in terminal, independent feed-in terminal does not need a multiplexer at a rear end for processing, thereby reducing signal power loss and decreasing the cost of the entire device. Besides, since antennas are integrated into each of single integrated antennas 100, 100A, there is no need to used different molds to manufacture different types of antennas, thereby reducing the manufacturing cost.
