A circularly polarized antenna with a low profile, small size, and light weight is required in mobile communication and wireless LAN systems. The purpose of this paper is to propose a small size circularly polarized annular microstrip antenna with a strip line in the inner circle. The proposed annular patch antenna can achieve circular polarization without the need for a 90/spl deg/ hybrid coupler. The calculated results using an electromagnetic simulator are described to demonstrate the… CONTINUE READING
