There is provided an antenna arrangement. The antenna arrangement comprises a baseband chain. The antenna arrangement comprises an antenna array. The antenna array is coupled to the baseband chain and divided into a first sub-array and a second sub-array. The first sub-array comprises antenna elements of only a first polarization and the second sub-array comprises antenna elements of only a second polarization. The first sub-array and the second sub-array have their antenna elements at identical locations relative each other, except for the antenna elements of the first sub-array and the antenna elements of the second sub-array being translated, but not rotated, relative each other.

This application provides an antenna assembly, including two antenna boards that are placed in a stacked manner. Polarization manners of the two antenna boards are perpendicular to each other, and the two antenna boards are configured to separate a received electromagnetic wave into a horizontal polarization component and a vertical polarization component. A bias voltage is applied to a liquid crystal dielectric layer in the two antenna boards to change ratios of reflection power to transmission power of the two antenna boards, to change a ratio of reflection power of the two polarization components that are obtained through separation, and implement linear polarization at different angles after vector synthesis is performed on the two polarization components. In this way, receive power of an antenna is increased.

An electronic device may be provided with a phased antenna array having a bent dielectric resonating element. The bent dielectric resonating element may have a first segment, a second segment nonparallel to the first segment, and an angled surface that couples the first segment to the second segment. One or more feed probes may be coupled to the first segment to excite the dielectric resonating element. A reflector may be provided on the angled surface to direct electromagnetic energy from the first segment to the second segment and vice versa. The bent dielectric resonating element may exhibit less overall height than dielectric resonators having straight columns of dielectric material, thereby allowing for a reduction in the thickness of the electronic device. The angled surface and the reflector may optimize the radio-frequency performance of the antenna despite the reduction in overall height.
