Abstract: This paper modifies the non-radiation edge of a rectangular microstrip radiator to push the resonant frequency upward and simultaneously increase its gain. The modification of the non-radiating edge increases the physical length of the edge, but reduces the electrical current path length, which is responsible for the push of the resonating frequency. For the change in resonating frequency, the work proposes an empirical formula. The modification of non-radiating edges results in a biconcave shape for the radiator. The push of the resonating frequency results in a decrease of wavelength, which leads to increased electrical size of the patch. Therefore, effective radiating aperture increases leading to improvement in gain and efficiency of the radiator. Simulated and measured results on fabricated prototype follow each other. The realized gain of the fabricated prototype is 5.0 dB at 4.19 GHz. This antenna has potential for use in various C band application areas like satellite communication, automobiles, radar, etc.
