Dual Band Circularly Polarized Slot Antenna Loaded with Asymmetric Cross Strips
In this paper, a dual band circularly polarized (CP) slot antenna loaded with asymmetric cross strips is proposed. It consists of a corner perturbed slot and two asymmetric strips oriented diagonally with the slot. The slot antenna is excited by $50\Omega$ microstrip line. The proposed antenna resonates at 2.7 GHz and 3.2 GHz. Two orthogonal degenerate modes produced by the perturbed slot antenna gives CP in lower band and the combination of slot and strip mode gives CP in upper band. The proposed antenna is fabricated and experimentally verified with axial ratio (AR) bandwidth of 13.27% and 13.31% in lower and upper band respectively. The peak gain of 4.68 dB at lower band and 4.81 dB at upper band is achieved. The simulated and measured results are in well agreement and it is good candidate for WiMax and WLAN applications.
