Abstract :
This paper investigated the capability of Electromagnetic band gap (EBG) in reducing the backlobe of the microstrip patch antenna array. Four different size of EBG have been simulated and the radiation patterns are presented. The results show that if only one slot of antenna is inserted into the structure, (3mm×6mm) EBG produced the best back lobe reduction that is from -10.24db to -17.67dB. If the number of slot of EBG increased up to 9 columns, only (3mm×3mm) EBG has shown an improvement while for the other size, the back lobe is getting worse.
