Differential Probe Fed Liquid Crystal-Based Frequency Tunable Circular Ring Patch Antenna

A differential probe-fed liquid crystal (LC)-based frequency tunable circular-ring patch antenna is presented. Besides, cavity model is extended to analyze the LC-based antenna for the differential operation. According to the cavity model, the permittivity and loss tangent of the LC are extracted fr...
