Abstract: A four-element modified rectangular microstrip array antenna (4MRMSAA) is designed and further extended to eight element modified rectangular microstrip array antenna (8MRMSAA). A comparative study is made between the proposed antennas. The experimental results show that 4MRMSAA operates for multi band and 8MRMSAA operates for wide band with an improvement (39.34%) in impedance bandwidth. This improvement in the impedance bandwidth of 8MRMSAA is 13.80 times more as compared to single rectangular radiating element (RMSA). The experimental results of the proposed antennas have been presented in terms of impedance bandwidth, return loss, gain, half power beam width (HPBW) and cross polarization levels. These multi band and wide band antennas have applications in modern communications and radar communication systems.
