Abstract
An electronic device may be provided with a phased antenna array and a display cover layer. The phased antenna array may include a probe-fed dielectric resonator antenna. The antenna may include a dielectric resonating element mounted to a flexible printed circuit. A feed probe may be formed from a patch of conductive traces on a sidewall of the resonating element. The feed probe may excite resonant modes of the resonating element. The resonating element may convey corresponding radio-frequency signals through the display cover layer. An additional feed probe may be mounted to an orthogonal sidewall of the resonating element for covering additional polarizations. Probe-fed dielectric resonator antennas for covering different polarizations and frequencies may be interleaved across the phased antenna array.
