This letter presents a broadband reflector based on a monopole‐type excitation structure. Using a moment method to optimize the different parameter structures, it is possible to use this structure on several gigahertz in a polarization diversity manner. Several structures are proposed. On average, it has been seen that we could obtain, from 2 to 5 GHz, an average gain of 8 dBi, a matching always better than 10 dB, and an axial ratio around 3 dB. The structure also could be adjusted for special frequencies by optimizing a few physical parameters. This antenna is interesting for use in indoor experimental communication systems as a test for polarization diversity. ©2000 John Wiley & Sons, Inc. Microwave Opt Technol Lett 24: 350–354, 2000.
