Circularly polarized dielectric resonator antenna for UMTS and WLAN applications

A circularly polarized dielectric resonator antenna (CPDRA) configuration is proposed, analyzed, investigated, and optimized using the CST-MW-simulator. The presented antenna is fed by a microstrip sequential phase power divider (MSPPD). Both microstrip and DRA have numerous benefits in wireless communication and radar systems applications. This is due to their small size, low cost, less weight, easy fabrication, and excellent compatibility with the typical manufacturing process of planar circuits. With the rapid progress of wireless technology, satellite communication systems use circularly polarized (CP) antennas to overcome the problems of mobility and weather conditions.
