ABSTRACT:
This invention comprises sn inexpensive, flush-mounted microstrip antenna e polarization of which is easily changed from vertical linear to horizontal linear, left-circular, right-circular or any desired elliptical sense. This enables the designer to select the polarization by selecting the proper location of shorting posts in the antenna. The use of rf switching diodes in place of conventional shorting posts provides a means of electronically switching the polarization.
