Abstract
An antenna includes a piezoelectric disc. The antenna further includes a first electrode disposed on a first surface of the piezoelectric disc and a second electrode disposed on a second surface of the piezoelectric disc that is opposite to the first surface. The first electrode and the second electrode are to receive a time-varying voltage to excite a mechanical vibration in the piezoelectric disc, and the piezoelectric disc is to radiate electromagnetic energy at a particular frequency responsive to the mechanical vibration.
