Gridded circular patch antennas

The performance of circular microstrip patch antennas is presented where the conducting patch and ground plane are constructed from a grid. Improved cross polarization, mode suppression, and bandwidth are possible, but are accompanied by lower gain and reduced front‐to‐back ratios. A computer simula...

Description
Summary:The performance of circular microstrip patch antennas is presented where the conducting patch and ground plane are constructed from a grid. Improved cross polarization, mode suppression, and bandwidth are possible, but are accompanied by lower gain and reduced front‐to‐back ratios. A computer simulation reveals the current structure. The density and shape of the grid pattern are important parameters. Such antennas are can be manufactured within glass laminates. ©1999 John Wiley & Sons, Inc.
