Abstract: An antenna array may include a plurality of printed circuit boards (PCBs) oriented in a stacked arrangement, parallel to and spaced apart from one another. Each of the PCBs may include a linear array of antenna elements, which cooperate with the linear arrays of antenna elements on other PCBs to form a two-dimensional array of antenna elements. The PCBs may be supported at one end by a common backplate in a cantilevered manner, with the linear arrays of antenna elements located near the free end of the PCBs. The PCBs may include a thicker portion and a thinner portion, and the thinner portion may include a heat sink or other thermal dissipation structure.

Abstract: Low-profile multi-antenna assembly. In one embodiment, the multi-antenna assembly includes UHF antenna elements and a wire loop antenna element that are each coupled to a multi-antenna printed circuit board (“PCB”). A portion of the UHF antenna elements and the wire loop antenna element are arranged to be coplanar with one another. The multi-antenna assembly also includes cellular antenna elements and one or more Wi-Fi antenna elements that are disposed on the multi-antenna PCB. A radiating portion of the cellular antenna elements and the one or more Wi-Fi antenna elements are arranged in parallel with the UHF antenna elements and the wire loop antenna element. A portion of the cellular antenna elements and the one or more Wi-Fi antenna elements are arranged on the multi-antenna PCB such that they do not overlap with feed portions of the UHF antenna elements. Methods of manufacturing and installing the multi-antenna assembly are also disclosed.

Abstract: The disclosed 20 dBi KSF300. A high gain 5th generation mobile network or wireless system (5G) technology fan beam antenna array offers a wide 3 dB beamwidth for wide angular coverage in azimuth with most of the energy focused within 44° of the main beam. Since propagation losses at Ka band are 20× more than at 6 GHz, the beamwidth of the antenna is reduced when the antenna gain increases. To alleviate this problem, the fan-beam type antenna can be useful to provide simultaneously high gain and wide azimuth coverage.
