A Compact and Wide Band Microstrip Patch Antenna for X-Band Applications

In this paper a coaxial probe feed modified swastika shape patch antenna is designed and analyzed by using the finite element method based High Frequency Structure Simulator (HFSS) and Method of Moment based Applied Wave Research (AWR) Microwave Office simulation tool. Proposed Structure is investigated for different dimensions (Length and Width) of rectangular slots cut from the patch antenna to obtain the broadband frequency range in X-band (8-12 GHz). The impedance bandwidth of the proposed antenna is 16.42% with centre frequency of 9.5 GHz at-10 dB, which is further improved to 17.89% after the parametric analysis of different dimensions of the rectangular slot cuts made on the patch antenna. The simulated radiation pattern (Electric field and Magnetic field), radiation efficiency, gain (in dB), VSWR (in dB) and return loss (S11 in dB) are demonstrated for proposed structure.
