DETAILED DESCRIPTION

Reference now will be made in detail to embodiments, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the embodiments, not limitation of the present disclosure. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made to the embodiments without departing from the scope or spirit of the present disclosure. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that aspects of the present disclosure cover such modifications and variations. As used herein, the use of the term “about” in conjunction with a numerical value is intended to refer to within 10% of the numerical value.


Example aspects of the present disclosure provide a technique to simplify the ceramic antenna manufacturing process and cost reduction. Traditionally, to fabricate the ceramic antenna, metal plating may be done on a ceramic dielectric carrier. Sometimes a vertical metal sidewall is included in ceramic antenna design to achieve a desired radiation performance at a certain frequency band. The mass production of this type of ceramic antenna with vertical metal walls is complicated and expensive as it may require multiple steps of metal plating. The manufacturing process of such antennas can be simplified and cost can be reduced significantly by replacing the vertical metal wall with multiple VIAs. The VIAs couple the top and bottom metals of the carrier similar to the vertical metal wall. Moreover, the antenna radiation performance is not impacted by VIA replacement.


Example aspects of the present disclosure are directed to antenna assemblies for use in, for instance, a wide variety of applications. The antenna assemblies may include an antenna (e.g., a Laser Direct Structuring (LDS) antenna) on a carrier (e.g., dielectric carrier, such as a ceramic carrier). The antenna assemblies may be configured to communicate over a variety of different frequency bands/protocols. For instance, the antenna assemblies may be configured to communicate, for instance, over frequency bands associated with LTE, Bluetooth, WiFi, GPS, or GNSS systems and/or protocols.


In some ceramic antenna designs, vertical metal sidewalls may be included to achieve a desired radiation performance at a certain frequency band. Production of this type of ceramic antenna with vertical metal sidewalls may require multiple steps of metal plating. According to example aspects of the present disclosure, multiple vias may be used in the place of vertical metal sidewalls to achieve a similar radiation performance at a certain frequency while reducing manufacturing costs of such antennas.



FIG. 1 depicts an example antenna assembly 100 according to example embodiments of the present disclosure. Those of ordinary skill in the art, using the disclosures provided herein will understand that antenna assembly 100 may include any suitable type of antenna with any operating frequency band. For example, antenna assembly 100 may include a GPS antenna (e.g., GPS ceramic antenna), such as a GPS L1 antenna with an operating frequency of about 1575 MHz or a GPS L5 antenna with an operating frequency of about 1176 MHz. As such, antenna assembly 100 may include a GPS antenna that operates at an L1 frequency band (e.g., about 1575 MHz) or at an L5 frequency band (e.g., about 1176 MHZ).


Antenna assembly 100 includes a carrier 110 (e.g., dielectric carrier). In some embodiments, carrier 110 may be a ceramic carrier. Carrier 110 has a first surface 112 and a second surface 114. The first surface 112 is opposite second surface 114. Carrier 110 also includes a plurality of sidewalls 116, 117, 118, and 119 connecting first surface 112 to second surface 114. Carrier sidewalls 116, 117, 118, and 119 may be defined as bare sidewalls, such that no metal structure is positioned on the sidewalls 116, 117, 118, and 119. Sidewalls 116 and 118 have length LSW1. Sidewalls 117 and 119 have length LSW2. In some examples, LSW1 is greater than LSW2. For example, carrier sidewalls 116, 118 may have a length (LSW1) of about 32 mm and carrier sidewalls 117, 119 may have a length (LSW2) of about 9 mm. As shown, carrier sidewalls 116, 118 may be greater in length than adjacent sidewalls 117, 119 of carrier 110.


In some embodiments, antenna assembly 100 may further include circuit board 140 (e.g., printed circuit board). As shown in FIG. 2, circuit board 140 may be coupled to carrier 110 (e.g., second surface 114 of carrier 110).


Antenna assembly 100 further includes an antenna pattern 120. The specific antenna pattern 120 illustrated in FIG. 1 is provided for purposes of illustration and discussion. Those of ordinary skill in the art, using the disclosures provided herein will understand that other antenna patterns may be used without deviating from the scope of the present disclosure.


Antenna pattern 120 may include multiple portions. For example, antenna pattern 120 may include first portion 125 positioned at least partially on first surface 112 of carrier 110. In some embodiments, first portion 125 may be metal plated onto first surface 112 of carrier 110. In some embodiments, the first portion 125 may be an LDS defined antenna portion.


Antenna pattern 120 further includes a second portion 130 extending perpendicularly from the first portion 125 through ceramic carrier 110 to the second surface 114. As shown, the second portion 130 may be defined as a plurality of vias 131, 132, and 133 (e.g., plurality of conductive vias) extending through ceramic carrier 110 from first surface 112 to second surface 114. The plurality of vias 131, 132, 133 is configured such that antenna assembly 100 may achieve a desired radiation performance.


The plurality of vias 131, 132, 133 may be positioned along a carrier sidewall 116, 117, 118, 119 such that the plurality of vias 131, 132, 133 is parallel to the carrier sidewall 116, 117, 118, and 119. As shown in FIG. 1, the plurality of vias 131, 132, 133 may be positioned along carrier sidewall 116 such that each via of the plurality of vias 131, 132, 133 is located at a distance 135 from an edge of antenna pattern 120 (e.g., first portion 125 of antenna pattern 120). In some embodiments, distance 135 may be in a range from 0.2 mm to 0.3 mm, such as 0.25 mm. The plurality of vias 131, 132, 133 (e.g., second portion 130 of antenna pattern 120) may directly contact (e.g., be electrically coupled to) first portion 125 positioned on first surface 112 of carrier 110.


In some embodiments, the second portion 130 may electrically couple the first portion 125 to one or more portions 121, 122, and 123 positioned on second surface 114 of carrier 110. As such, second antenna portion 130 may include multiple pluralities of vias 131, 132, and 133. The multiple pluralities of vias 131, 132, and 133 may be configured to electrically couple first antenna portion 125 positioned on first surface 112 of carrier 110 to a plurality of antenna portions 121, 122, and 123 positioned on second surface 114 of carrier 110. For example, the plurality of vias 131 may electrically couple first portion 125 positioned on first surface 112 of carrier 110 to third portion 121 positioned on second surface 114 of carrier 110. The plurality of vias 132 may electrically couple first portion 125 positioned on first surface 112 of carrier 110 to fourth portion 122 positioned on second surface 114 of carrier 110. The plurality of vias 133 may electrically couple first portion 125 positioned on first surface 112 of carrier 110 to fifth portion 123 positioned on second surface 114 of carrier 110.


While three pluralities of vias 131, 132, and 133 and three antenna portions 121, 122, and 123 are depicted in FIG. 1, those skilled in the art will understand that second portion 130 may include any number of pluralities of vias electrically coupling first portion 125 to any number of portions positioned on second surface 114 of carrier 110 without deviating from the scope of the present disclosure.


The second portion 130 (e.g., multiple pluralities of vias 131, 132, and 133) of antenna assembly 100 may be used to replace a vertical sidewall (e.g., metal sidewall). For example, FIG. 3 depicts a vertical sidewall antenna assembly 200. As shown in FIG. 3, the vertical sidewall antenna assembly 200 includes a first antenna pattern 220 positioned on a first surface 212 of the carrier 210. A vertical sidewall 230 (e.g., metal sidewall) is positioned on carrier sidewall 216 to achieve a desired radiation performance at a specified frequency band.


Production of vertical sidewall antenna assemblies 200 may be expensive due to vertical sidewall 230. Vias 131, 132, and 133 may be used instead of vertical sidewall 230 to achieve a similar desired radiation performance at a specified frequency band with a lower production cost.
