Abstract :
In this paper we present a frequency tunable patch antenna working in the Ka-band. Liquid Crystals are used as a tunable dielectric layer between a ground plane and an inset feed microstrip patch. Measurements show, that the resonance frequency of the antenna can be tuned continuously from 34.1 GHz to 37.7 GHz with bias voltages between 0 and 90 V.
