Abstract
A frequency tunable CPW-fed slot dipole using a piezoelectric transducer (PET) is presented. A dielectric perturber attached on a PET is used to change the effective dielectric constant of the slot line at the slot dipole. The electrical length of the slot dipole is changed due to the variation of the air gap between the slot dipole and the perturber by an external voltage. The resonant frequency of the slot dipole is tuned over 300 MHz from 4.65 to 4.35 GHz using an external voltage of 60 V.
