Abstract :
A novel compact multi-band design of planar C-shape monopole antenna with inverted L-shape 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 25 % antenna size reduction. The measured peak gains and radiation efficiencies are about 1.6 / 1.9 / 2.9 dBi and 91 / 96 / 94 % for the 2.6 / 3.5 / 5.5 GHz operating band, respectively, with nearly omni-directional pattern.
