Abstract :
A ring cavity antenna for a wide beamwidth pattern which does not use high-dielectric materials is presented. Antenna characteristics calculated by the cavity model showed that the ring cavity antenna has a wide beamwidth. Theoretical values are also verified by the measured radiation pattern and input impedance.<>
