Abstract :
A four-point fed radial line planar antenna (RLPA) array which has the capability of monopulse tracking operation is proposed. A simple analytical model which describes the performance of the array is presented. A four-point fed radial line power divider which has 90 output port probes was fabricated. Sum and difference patterns evaluated from the measured transmission amplitude and phase data are shown verifying the capability of the four-point fed RLPA for monopulse tracking operation.<>
