主 题：Circularly polarized DRA ARBW bandwidth gain radiation efficiency
摘 要：In this work,a novel compact wideband reconfigurable circularly polarised(CP)dielectric resonator antenna(DRA)is *** L-shaped Dielectric resonator antenna is excited by an inverted question mark shaped *** arrangement of feed-line helps to generate two orthogonal modes inside the DR,which makes the design circularly polarised.A thin micro-strip line placed on the defected ground plane not only helps to generate a wideband response but also assist in the positioning of the two diode *** switches located at the left and right of the micro-strip line helps in performing two switching *** novel compact design offers the reconfigurability between 2.9–3.8 GHz which can be used for different important wireless *** the switching operation I,the achieved impedance bandwidth is 24%while axial ratio bandwidth(ARBW)is 42%.For this switching state,the design has 100%CP ***,the switching operation II achieves 60%impedance bandwidth and 58.88%ARBW with 76.36%CP *** proposed design has a maximum measured gain of 3.4 dBi and 93%radiation *** proposed design is novel in terms of compactness and performance *** prototype is fabricated for the performance analysis which shows that the simulated and measured results are in close agreement.
