Designing of innovative Co planar waveguide fed slot antenna for specific K-band and comparing its gain with rectangular patch antenna

The study’s objective is to develop a CoPlanar Waveguide (CPW) fed slot antenna for the K-band in HFSS and evaluate its performance in comparison to that of a conventional Rectangular Patch Antenna. CoPlanar Waveguide (CPW) fed slot antenna and Rectangular Patch Antenna (RPA) are constructed in Ansoft HFSS using a dataset of 20 samples and a pretest power of 80%, respectively. The gain of the Rectangular Patch Antenna is 1.82 dB, while that of the Innovative CoPlanar Waveguide fed slot antenna is 3.83 dB. Based on an independent sample t-test, the mean gains for the CPW and the Rectangular Antenna in the proposed design are 2.5685 and 6.6130, respectively. Gain is statistically significant at the 0.005 level (p0.05). The results of this study show that the performance of an innovative CoPlanar Waveguide fed slot antenna is 32% better than that of a Rectangular Patch Antenna design.
