Abstract :
In this paper, a wideband planar multi resonator antenna with parasitic coupling is proposed and studied. Impedance and radiation characteristics of this antenna are presented and discussed. From the results, it has been observed that, the Impedance bandwidth, defined by 10 dB return loss, can reach an operating bandwidth of 251 MHz with center operating frequency of 3023 MHz, which is about four times that of conventional reference patch antenna. The gain of studied antenna is also observed with peak gain of about 8.33 dBi.
