Abstract:
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 at least 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, wherein the radiator is between the ground plane and the piezoelectric assembly in a layered arrangement, the piezoelectric assembly being either in conductive contact with the radiator or electrically coupled with the radiator and not in conductive contact with the radiator, wherein the piezoelectric assembly, the radiator, the ground plane, and the feed post together form an antenna configured to produce and receive electro-magnetic radio-frequency signals; a first housing portion of a wearable device; and a second housing portion of the wearable device and mated to the first housing portion, wherein the radiator is supported in a recess between the first housing portion and the second housing portion, the recess being positioned outside a display cover of the wearable device.
