Abstract :
In this paper, a novel and simple dual-band planar omni-directional antenna is proposed. Through proper adjustment of the couplings between the two coupling arms and the main dipole-based radiating section, the proposed antenna can operate either in the wideband mode or dual-band mode. Operated in the dual-band mode, the proposed antenna is able to cover both 3.25~3.85 GHz and 5.25~5.85 GHz for WiMAX applications with S11 less than -10 dB. Omnidirectional radiation patterns and maximum gain of 2.0 dBi at both bands were also achieved.
