Abstract

This paper presents design and development of 2 × 1 linearly polarized microstrip array antenna with Electromagnetic band gap (EBG) structure to improve bandwidth and suppression of back lobes in radiation pattern. The array elements are fed by corporate feed network, which improves the impedance bandwidth of the 2×1 rectangular microstrip array antenna by 8.342% and inclusion of EBG lattice reduces the back lobes in radiation characteristics. Experimental results for the array antennas in terms of return loss, radiation pattern, -3dB beam width, and suppression of back lobes are presented.
