Abstract: An electronic device may be provided with a phased antenna array that radiates at a frequency greater than 10 GHz. The array may include a dielectric resonator antenna having a dielectric column with non-planar sidewalls that include planar portions and corrugated portions with grooves and ridges, that include sidewall steps, and/or that include angled sidewall portions. The dielectric resonator antenna may include a first dielectric column and a second dielectric column stacked on the first dielectric column. The second column may be narrower and may have a higher dielectric constant than the first column or may have the same width but a lower dielectric constant than the first column. This may serve to broaden the bandwidth of the dielectric resonator antenna relative to scenarios where the dielectric resonator antenna includes only a single dielectric resonating element having only planar sidewalls.

Abstract: An electronic device may include an antenna and a coaxial cable coupled to the antenna. The coaxial cable may have a signal conductor coupled to an antenna resonating element of the antenna and a ground conductor coupled to an antenna ground of the antenna. The ground conductor may include an ungrounded segment that is separated from the antenna ground by a gap. A capacitive coupling between the ground conductor in the ungrounded segment and the antenna ground via the gap may form an impedance matching component for the coaxial cable. A dielectric retention layer may overlap the coaxial cable and hold the coaxial cable in place relative to the antenna ground to maintain the gap.
