Surface Wave Minimizing in 2x2 Microstrip Antenna Array

Huda Sh. Gally, Zeki A. Ahmed, Ahmad H. Abood


Key research area is improving band width and gain in design of microstrip patch antennas. reducing surface waves, which can be excitation in patch antennas, by using Electromagnetic Band Gap (EBG) structures ,which increasing the band width and gain . The surface of EBG are selective in supporting surface waves. The paper analyses the performance of 2x2 microstrip antenna array with and without EBG cells . It is observed the performance of the 2x2 antenna array with EBG is found to be better as compared to microstrip antenna array without EBG . Simulation results show improvements in the band width and gain, redusing surface wave means reduction in mutual coupling between elements in antenna array. in this work using HFSS software to simulated the antennas array .

Keywords: (EBG), Microstrip antenna array ,Mutual coupling , Surface waves, HFSS .
