Abstract: Radiating elements and antenna arrays are disclosed, such as antenna array that includes a first and second vertically-extending and adjacent arrays spaced apart from each other by a first equivalent distance. Two adjacent radiating elements in the first array and/or the second array are spaced apart by a second equivalent distance. The first equivalent distance is not equal to the second equivalent distance. A radiating element may have an asymmetric radiator having a first extending dimension in a first direction and an unequal second extending dimension in a second direction perpendicular to the first direction. The first equivalent distance has a first ratio with respect to the second equivalent distance, and the first extending dimension has a second ratio with respect to the second extending dimension. The second ratio is set to match the first ratio.

Abstract: A housing for a cavity phase shifter comprises a first part that extends along the length of the cavity phase shifter and a separate second part that extends along the length of the cavity phase shifter. The first part comprises a substantially flat first base and first arms that extend from the two widthwise edges of the first base toward the second part and the second part comprises a substantially flat second base and second arms that extend from the two widthwise edges of the second base toward the first part. The first arms and the second arms at least partially overlap and are capacitively coupled to each other to form the first cavity of the cavity phase shifter.

Abstract: RF signal transmission devices for a base station antenna include a printed circuit board which has a dielectric layer, a metal pattern layer on a first main surface of the dielectric layer, and a ground layer on a second main surface of the dielectric layer. The metal pattern layer has a transmission line deformation section for enhancing the ability to withstand surge current, and the ground layer comprises a groove that is configured to at least partially compensate for the change in the characteristic impedance due to the transmission line deformation section. The RF signal transmission device can achieve good characteristic impedance matching whilst enhancing the capacity to withstand surge current. In addition, the RF signal transmission device can improve PIM performance. The present disclosure also includes a phase shifter for a base station antenna and a base station antenna.
