ABSTRACT In this article, a new compact Circularly Polarized Antenna with wide operating bandwidth is proposed. The proposed structure consists of a Modified Circular Split Ring Resonator (MCSRR) as the radiating patch, which is fed by coplanar waveguide and loaded with 2 × 2 closed-ring resonantor (CRR) array on its FR4 epoxy substrate. The dimensions of the antenna are 0.329 λo x 0.329 λo x 0.024 λo (λo stands for the free space wavelength at center frequency of 4.94 GHz).The implementation CRR on modified printed monopole antenna leads to a wide measured impedance bandwidth of 2726 MHz with a peak gain of 5.09dBi and efficiency of 96.3% in the operating bandwidth. A prominent feature of the proposed antenna is that dual 3-dB axial ratio bandwidth of 430 MHz and 670 MHz is observed in the operating band, and thus, making it to be a promising candidate for recent day wireless applications. The simulated results was verified by measuring the characteristics of the fabricated antenna; the obtained results showed a good matching with the simulated results.
