A novel design of integrated compact band-selective filter with CoPlanar Waveguide-fed CPW Ultra-WideBand antenna (UWB) using Liquid Crystals Substrates for microwave applications is presented. This combined system based on cascaded technique is used to reduce the cost and the overall volume of RF front-end subsystem especially in wireless communication systems. The proposed reconfigurable antenna based on LCs without filter satisfies the return loss requirement of less than -20dB over the frequency range of 3.1GHz to 11GHz with variation of the simulation resonance frequency of 1.2GHz corresponding to a frequency agility of 26.08%.
