Gain improvement and return loss reduction of microstrip patch antenna at 12GHz using rogers RT/Duroid (TM) substrate in comparison with FR-4 epoxy substrate.

The primary goal of this project is to optimize the Gain and decrease the Return Loss of a rectangular microstrip patch antenna operating at 12GHz by experimenting with different substrate materials. A total of 20 individuals, split into two groups, each employ a microstrip patch antenna using a microstrip line feed method built on either a FR-4 Epoxy substrate or a Rogers RT/Duroid substrate. Microstrip patch antenna gain and return loss are optimized using HFSS simulation software, and differences between substrate materials are highlighted. At a frequency of 12 GHz, the simulation results show that the planned antenna gain is 6.6046 dB for a FR-4 epoxy substrate and 9.9099 dB for a Rogers RT/Duroid substrate. The antenna mounted on a FR-4 epoxy substrate has a return loss of -24.8293 dB, but one mounted on a Rogers RT/Duroid substrate is just -33.0853 dB, suggesting significant improvement. Gain has a significance value of 0.043, whereas return loss has a value of 0.039, according to the statistical analysis. Microstrip Patch Antenna using microstrip line feed technology on Rogers RT/Duroid substrate seems to have better performance characteristics than Microstrip Patch Antenna on FR-4 Epoxy substrate. The findings indicate that the suggested antenna is suitable for usage in Satellite Communications and other Ku-band applications. [ABSTRACT FROM AUTHOR]
