Abstract

AbstractA novel structure of microstrip patch antenna is presented for high gain enhancement and broadband wireless applications. The manuscript describes a comparative analysis of the patch antenna with the multiple split-ring resonators loaded patch antenna. The design performance was examined using different parameters like return loss, frequency resonance, voltage standing wave ratio, gain, and directivity. Gain enhancement is possible by enabling diffracted ground in the ground layer. The metamaterial behavior of the antenna is observed by a negative refractive index for complementary split-ring resonators (CSRR) structure. The coaxial feed is given to the antenna for excitation. The proposed design provides the return loss of −29 dB, voltage standing wave ratio (VSWR) of 1.08, and total gain of 8.34 dB. Results are authenticated by physical designing of the antenna and measuring results using a vector network analyzer. The proposed antenna structure will be used for a satellite TV network, weather radar station, Terrestrial microwave links under C band applications.KeywordsGainMetamaterialComplimentary split-ring resonatorMicrostrip patch antenna
