Abstract: An electronic device may be provided with an antenna that radiates through a rear housing wall in multiple frequency bands. The antenna may have one or more directly fed patches and one or more indirectly fed patches that are indirectly fed by the directly fed patch(es). One or more of the patches may be shorted to ground traces through the substrate using conductive vias. The antenna may be provided with a dielectric block mounted to the substrate. The patches may be sandwiched between the substrate and the dielectric block. The dielectric block may have a higher dielectric constant than the substrate. The dielectric block may contribute one or more dielectric resonator antenna (DRA) modes to the resonances of the antenna. In these implementations, the patches in the antenna resonating element may form a feed probe for the dielectric block.
