Abstract :
This paper presents a tunable Artificial Magnetic Conductor (AMC) unit cell design by means of four copper strips. With the inclusion of copper strips, the initial reflection phase of dual band AMC changes from 2.45 GHz and 5.8 GHz to single frequency of 3 GHz. To facilitate the tunable function on antenna performance, an Ultra-Wideband (UWB) antenna has been designed and analyzed. Performance comparison is carried out with and without incorporation of AMC. The AMC is tuned to change frequency using copper strips. Result in terms of reflection phase, return loss and radiation pattern are discussed.
