Abstract: In this paper we have presented the comparative study and theoretical validation of two element slot loaded rectangular microstrip array antenna (TS-RMAA) and two element slot loaded equilateral triangular microstrip array antenna (TS-ETMAA), fed by corporate feed technique illustrating wide band operation. The experimental results reveal that, the impedance bandwidth of TSRMAA is 6.54% (i.e., 700 MHz) and the impedance bandwidth of TS-ETMAA is 7.35% (i.e., 820MHz). The impedance bandwidth of TS-ETMAA is 1.12 times more than the impedance bandwidth of TS-RMAA. The theoretical impedance bandwidth is determined to compare the experimental impedance bandwidth for validation. The theoretical and experimental impedance bandwidth is in close agreement with each other. The wide band operation of the antenna may find application in communication system.
