Study and analysis of SQMSA with square shaped Defected Ground Structure: Performance enhancemment and virtual size reduction

In this study, a conventional square shaped edge feed patch antenna is designed for 5GHz frequency. The conventional design is then embedded with the square shape defect on the ground plane. The parameters like resonating frequency, return loss, VSWR, Virtual size reduction is done. It is found that the antenna embedded with Defected Ground Structure (DGS) is working in multiband frequency with proper impedance match and more it's found that there is improvement in other parameters. Virtual size reduction is obtained up to 90% compared to conventional. It's found that these antennas can be used for C and L band applications. Antenna works for multiband frequencies with proper impedance matching it's also found that antenna resonates in X-band with C-band frequency. Antennas are simulated using High frequency simulator software (HFSS) and are tested on Vector Network Analyzer (VNA), for practical parametric test.
