## Abstract A singleβfeed TM~21~βmode circular patch antenna with circular polarization (CP) is proposed and investigated. The operating condition for CP in the antenna is theoretically determined and experimentally validated. An impedance bandwidth of 10% (SWR β€ 2) and an axial ratio bandwidth of

In this paper, the design of a broadband dual-polarized microstrip patch antenna with excellent polarization purity is investigated theoretically and experimentally. Based on cavity-model theoretical analysis, a test dual-polarized microstrip patch antenna fed by double slot-coupled feeds with a 180
## Abstract A novel design of a broadband circularly polarized square slot antenna fed by a single coplanar waveguide is proposed and discussed. The circularly polarized radiation is achieved by means of using an outer rectangular ring and an inner rectangular ring at the center of a square slot. T
