Abstract:

This paper introduces a novel approach to create notch band within ultra-wideband (UWB) communication systems based on a modified mushroom electromagnetic band gap (EBG) structures. The concept presented here can be implemented in any structure that has a microstrip in its configuration. The modified edge-located vias EBG structure is characterized and analyzed using CST Microwave Studio full wave electromagnetic solver and then optimized to work at WiMAX band (3.3 – 3.7 GHz). A double layer Antipodal Vivaldi Antenna is used to demonstrate the applicability and effectiveness of the novel EBG notch band feature. Simulation results achieved a band notch at 3.18 GHz – 3.80 GHz within the 2.78 GHz to more than 12 GHz operating band of the antipodal Vivaldi antenna which demonstrated the effectiveness of the proposed structure.
