Directivity & VSWR Enhancement of Microstrip Patch antenna at 9.45GHz for Different Substrate Thickness variations in Comparison with Conventional 1.6mm Substrate thickness

In this manuscript a rectangular-shaped microstrip patch antenna (MPA) at a frequency of 9.45GHz by varying the thickness(1mm, 1.2mm, 1.4mm, 1.8mm)of the substrate to enhance the Directivity and VSWR of the antenna. With a sample size of 20, a MPA with microstrip line feed method and varied substrate thickness is employed. Directivity and VSWR of the Microstrip patch antenna are enhanced and highlighted using HFSS Simulation Software in contrast to a varied substrate thickness of the antenna. The Simulation Results obtained for the designed antenna are Directivity is 6.8420dB for 1mm, 7.4130dB for 1.2mm, 7.6579dB for 1.4mm, 7.9129dB for 1.8mm and 7.9369dB for 1.6mm. VSWR is 3.01 for 1mm, 1.9 for 1.2mm, 1.60 for 1.4mm, 1.106 for 1.8mm and 1.20 for 1.6mm. Based on statistical analysis, the significance value for directivity is 0.094 and for VSWR is 0.078. Microstrip Patch Antenna Performance Parameters Using Microstrip Line Feed Technique for 1.8mm thickness substrate appears to be improved when compared with Conventional 1.6mm substrate thickness antenna. The suggested antenna is suitable for Wireless Network Communications as well as Multi-band applications.
