RECONFIGURABLE MICROSTRIP-PATCH ANTENNA WITH FREQUENCY AND POLARIZATION-DIVERSITY FUNCTIONS

摘要

The design of a novel reconfigurdble microstrip-patch antenna with frequency- and polarization-diversity functions is presented. A U-slot inserted into the square patch and a PIN diode are utilized to realize frequency-diversity operation. Polarization diversity between linear polarization (LP) and right-hand circular polarization (RHCP) is also provided by switching the two PIN diodes on the truncating corners of a square patch on and off. The designed antenna is implemented and the antenna characteristics are measured.
