Abstract

In this paper, a modified slotted patch EBG structure has been investigated and followed by a discussion of the design and the evaluation of the structure. The result of the EBG structure in term of S₂₁ is shown in simulation and measurement. The simulation process is being done using microwave office software 2006. The EBG structure is developed using inexpensive Fire Retardant-4 (FR4) board. The S₂₁ result shows that the band gap of the structure is between 2.24 GHz and 2.6 GHz at -20 dB. The structure is then incorporated into a 2 by 2 antenna array operates at 2.4 GHz with a separation between lambda2 and lambda. The result shows that the radiation pattern improved with reduced back lobe with an extra gain of 1 dB compared with the antenna without the EBG structure.
