摘要：
This article presents a CPW-fed planar monopole antenna with a small ground-plane size. The monopole antenna is a triple-band design and is meant for mobile handsets with WiFi and WiMAX features. The planar structure comprises an L-shaped monopole backed by a stub-loaded open-loop resonator. The proposed antenna features three bandwidths of 2.25-2.62 GHz, 3.25-4.97 GHz, and 5.2-6.30 GHz, which yielded the maximum gain of around 1 to 2 dBi. Reduction effects of ground-plane on antenna's performance rectified by the parameters of open-loop resonator are also investigated. The overall dimensions are 46 (W) x 34 (L) x 0.8 (d) mm(3).
