The need for directional antennas possessing high gain, wideband and circular polarization characteristics for different wireless applications has increased considerably. In this paper, a slotted coaxial line fed cavity backed u-shaped cross dipole antenna is developed to achieve wide bandwidth and reconfigurable circular polarization. The cross dipole consists of two orthogonal u-shaped dipoles. These dipoles are mounted on the outer conductor of the coaxial line. The feeding and tuning screws are used for impedance matching and increasing impedance bandwidth.
