Abstract

This paper investigated that resonant frequencies of microstrip patch antenna were tunable when piezoelectric materals were used as the antenna substrates. The resonant frequencies of the antenna using the piezoelectric substrate were able to be controlled by applied voltage. The frequency variation of the air gap antenna was 16MHz when the voltage variation was 13[KV/cm], and the frequency variation of microstrip patch antenna made of $LiNbO_3$ substrate was 11MHz when voltage variation was 480[V/cm].
