EM Optimization of an Inset-Fed Rectangular Microstrip Antenna as a Function of Inset Depth and Width for Wireless Communication

This paper presents modeling of an inset-fed rectangular patch antenna. The S and Z parameters of an inset - fed rectangular mocrostrip patch antenna are investigated and optimization is performed by varying the inset depth psilaDpsila of feed line with keeping inset width dasiaSpsila constant. Also varying the inset width dasiaSpsila of feed line while keeping inset depth dasiaDpsila constant. The impedance and radiation characteristics of rectangular patch antenna fed by an inset microstrip transmission line are examined and compared. We achieved a return loss less than -35 dB and VSWR equal to 1.29 at 2.3 to 2.4 GHz.
