High gain W-shaped microstrip patch antenna

A high gain W-shaped microstrip patch antenna is proposed and experimentally investigated. The patch antenna employs a new inverted W-shaped patch structure with meander probe feed technique. A prototype of the proposed antenna is fabricated and tested for validation. This low-profile antenna is operating for the frequency band of 1.84GHz to 2.29GHz. It exhibits an impedance bandwidth (2:1 VSWR) of 21.79% and a high gain of 10.46dBi at the frequency of 2.11GHz. The measured result shows the stable radiation characteristics, including a low cross-polarization level below -20dB in both planes.
