Abstract
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.
