Abstract :
A wideband unidirectional antenna element composed of a magnetic dipole and an electric dipole is designed. Simulated and measured results are presented. The antenna achieves an impedance bandwidth of 91% (SWR < 2). Due to the complementary nature of the antenna and the incorporation of a modified grounded structure, the antenna has a relatively stable broadside radiation pattern with low cross-polarization and low back-lobe radiation over the operating band. The gain of antenna is about 9.3 dBi.
