Performance of a 10 GHz circular patch antenna fed by an aperture coupled microstrip line

摘要

A circular patch antenna fed by an aperture coupled microstrip line has been demonstrated. The patch was enclosed by a cavity to reduce the surface wave interactions in an array environment and to improve heat dissipation when using active devices. A pedestal design was also implemented to help heat dissipation when using active microwave circuits. The antenna exhibited a 9.3% bandwidth from 9.55 to 10.48 GHz.
