A Novel Dual-Band Dual-Sense Circularly Polarized Slot Antenna Design

摘要：

　　This paper presents a novel dual-band dualsense circularly polarized slot antenna design.The dual-band is achieved using a single-layer bended microstrip-fed configuration coupled to two slots.The dual-sense circularly polarization is obtained by an asymmetric slot-ring and Lshaped microstrip-fed in a wide square slot.Simulated results show that the proposed antenna has good circular polarization characteristics for left-hand circularly polarization(LHCP)in the lower band and right-hand circularly polarization(RHCP)in the upper band.The 10dB return loss impedance bandwidths for the lower and upper band are 14.7%and 28.4%respectively.The 3-dB axial ratio(AR)bandwidths are 8.8%and 4.5%for the lower and upper band respectively.
