Abstract :
A new method for feeding a circular microstrip patch antenna with a 50/spl Omega/ microstrip feed line without causing a deterioration in the antenna radiation characteristics is reported. The input impedance tuning ability of this antenna makes it attractive as a radiating element in large phased arrays implementing a corporate feeding structure. The design consists of a sectoral slot and a shunt element on the circular patch. This structure shows a wide variation in input impedance along the circumference with reference to the slot.<>
