| 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. |
