Analysis and design of trapezoidal shape CSRR rectangular patch antenna for wireless communications.

A monopole rectangular shape patch antenna (RSPA) with trapezoidal shape complementary split ring resonator (CSRR) is designed for wireless communication application is presented in this paper. The trapezoidal shape CSRR is considered to obtain circular polarization and rectangular slit is considered to operate antenna for triple frequencies at 1.88, 4.17, and 6.73 GHz, respectively. The axial ratio of 1.25, 1.05, 1.28 dB is observed and a maximum gain of 6.29 dBi at 1.88 GHz frequency is produced. The RSPA model is designed for mobile and fixed satellite application.
