Abstract :
A new circularly polarized rectangular microstrip antenna using a proximity-coupled feed method is proposed in this paper. This antenna is fed by a microstrip line offset from the center of a rectangular microstrip antenna. The proposed antenna has no 90-degree hybrid coupler for circular polarization and allows easy connection between a microstrip line and an antenna element. The measured results verify the circular polarization and show that good return loss and axial ratio characteristics have been obtained
