Proximity coupled feed

WebbThis 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. WebbThe proximity feed microstrip antenna (PMA) fed via a gap enables switching of the polarization with a simple operation of opening or shorting the end of the feed. However, since the PMA is coupled electromagnetically with the feed line printed on the same surface as the antenna, the effect of the feed line on the antenna characteristics is …
