Abstract
Piezoelectric materials, particularly ones with high quality factor used for mechanical antenna implementations, are sensitive to environmental conditions including temperature swings, humidity, vibration. Under the varying environmental conditions, the resonant frequency of the piezoelectric antenna can drift, and this results in the dampened piezoelectric radiator performance due to the mismatch between RF source' excitation frequency and piezoelectric antenna's resonant frequency. The frequency drift can be detrimental to the operation of the communication system that involves piezoelectric transmitter/receiver as a system component. In embodiments, the piezoelectric antennas may be integrated into a crystal oscillator to lock a drive frequency of the piezoelectric antennas to a resonant frequency of the piezoelectric antennas.
