In this paper, wideband multilayer stacked resonators, combination of planner patches and stacked with defected ground plane in normal and inverted configuration are proposed and studied. Impedance and radiation characteristics 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 746 MHz with an average center operating frequency 2001 MHz, which is about 32 times that of conventional reference antenna. The gain of studied antenna is also observed with peak gain of about 9 dB.
