Simulated and measured results of a diplexing feed network for a wideband dual‐frequency stacked microstrip patch antenna are presented. The microstrip feed network is easy to design and consists of a T‐junction and a single decoupling resonator for each frequency band. The return loss in each of the frequency bands is better than 10 dB, over a better than 10% bandwidth. © 2002 Wiley Periodicals, Inc.
