Abstract :
A wideband unidirectional patch antenna composed of a shorted bowtie dipole with Γ-shaped feed and an L-shaped electric dipole is designed. It achieves an impedance bandwidth of 87% for VSWR ≤ 2 in the range 2.2-5.6 GHz, stable peak gain of around 7 dBi, unidirectional radiation patterns and low cross-polarisation over the whole operating band. It is sufficient for accommodating recent wireless communication services such as 3G, WiFi, WiMax, Bluetooth, Zigbee, etc.
