Abstract :
An Ultra Broadband Printed (UBP) antenna is presented which consists of a diplexer and two aperture stacked patch antennas. S-parameters theory is used to investigate the input impedance behavior of the UBP antenna. This antenna can produce a 10 dB return loss bandwidth of almost 120% with constant gain of 6.5 dBi. A uniform radiation pattern over entire band was also achieved
