Wide Band W-Shaped Microstrip Patch Antenna with Inverted U-Slotted Ground Plane For Wireless Applications
In this paper, a wide band antenna with W-shaped patch prototyped on FR4 substrate is proposed and analyzed. The antenna is fed by coaxial probe with an impedance matching of 50 ohms. A parametric study is performed by varying the feed location and the variations in return loss are observed. The simulation results of the parameters like VSWR, return loss, radiation pattern etc., satisfied the theoretical conditions. An impedance bandwidth if 24.5% (9.55 GHz - 12.18 GHz) is obtained with a ground plane having multiple inverted U-shaped slots. The model is analyzed using finite element method based ansoft high frequency structure simulator v.13.
