Abstract
The topic considered here is the design, achievement and test of a liquid crystal-based patch antenna. This device was realised in planar technology with low-cost foam substrate. Liquid crystal dielectric anisotropy permits frequency agility. Owing to technological difficulties of the foam, we used this dielectric property to adjust the shift of the antenna resonance frequency whenever required. The comparison of simulation and measurement data evidenced that frequency can be adjusted.
