Abstract

A compact multiresonator-loaded planar antenna for multiband operation is presented. Multiresonator-loaded structures including a pair of symmetrical edge resonators and a T-shaped stub resonator are employed. By loading these resonators, a U-shaped monopole antenna can yield three independent resonances while achieving a compact size of 18×19 mm². The experimental results demonstrate that the proposed antenna is capable of operating over the 2.40-2.51 GHz, 3.35-3.94 GHz and 5.02-6.63 GHz frequency ranges, which is suitable for WLAN 2.4/5.2/5.8 GHz and WiMAX 3.5 GHz applications.
