A low-profile, compact and frequency-tunable antenna made on ferroelectric substrate is presented. It is designed as a planar dipole antenna with an IDC varactor integrated in the signal line. Antenna is fed through a coplanar waveguide matched to 50 Ω. The center frequency can be tuned from 6.895 GHz to 7.050 GHz. It exhibits elliptical polarization and omnidirectional radiation pattern.
