Abstract :
An ultra-wideband (UWB) microstrip antenna with notch capability and a bandwidth of 3 GHz to 25 GHz is presented. The notch is created by adding an electromagnetic band gap (EBG) structured that is coupled to the antenna feed line via a ground plane slot. The design of these elements follows microwave filters design principles. The relevant parameters to design and tune the notch band are identified. The performance of the antenna is demonstrated through the reflection coefficient, gain, radiation patterns, and magnitude and group delay responses. The initial antenna design is verified by the commercial field solver packages CST and HFSS.
