Abstract :
A small wide-band patch antenna with double shorting walls is presented. By employing two shorting walls and an additional aperture on the upper patch of a folded patch feed antenna, a 0.365/spl lambda//sub 0/ patch antenna with impedance bandwidth of more than 70% (VSWR/spl les/2) is achieved experimentally. Measured radiation patterns and gain across the frequency band are given.
