Claim:
1. An apparatus comprising: a ground plane; a radio-frequency radiator, the radiator offset from the ground plane in a direction substantially normal to the ground plane by a first distance; a feed post conductively connected to the radiator; and a piezoelectric assembly offset from the ground plane in a direction substantially normal to the ground plane by a second distance, the piezoelectric assembly configured to couple inductively with the radiator and being separated from the radiator by at least a housing structure of the apparatus, wherein the piezoelectric assembly, the radiator, the ground plane, and the feed post together form an antenna configured to produce electro-magnetic radio-frequency signals and receive electro-magnetic radio-frequency signals.
