Abstract

A novel compact multi-band design of planar C-shaped monopole antenna with inverted L-shaped parasitic strip is proposed for IEEE 802.16m WiMAX system. The obtained impedance bandwidth across the 2.6/3.5/5.5 GHz operating bands can reach about 240/570/4470 MHz, respectively. Only with the antenna size of 15×30×0.8 mm³, the proposed monopole antenna has the compact operation with more than 50% antenna size reduction. The measured peak gains and radiation efficiencies are about 2.1/2.2/2.9 dBi and 91/96/94% for the 2.6/3.5/5.5 GHz operating band, respectively, with nearly omni-directional pattern in the XY-plane.
