Circularly polarization can also be achieved by designing a corner truncated square patch, a circular patch with cross slot, or micro strip fed proximity couple ring design [13-14], a single probe fed METALLIC CAVITY ANTENNA FED WITH AN L-SHAPED PROBE CP radiators are needed for CP radiation in these designs where the cavities only serve as reflectors. Open-ended waveguide antennas with linear polarization [12, 13] are attractive candidates to realize electrically large size antenna and strong
Abstract: A new design of a microstrip-line-fed circularly polarized printed ring slot antenna is proposed. Circular polarization (CP) radiation of the proposed design is achieved by introducing proper asymmetry in the ring slot structure and feeding the ring slot using a microstrip line at 45/spl deg/ from the introduced asymmetry.

Abstract: A substrate-integrated waveguide (SIW) cavity-backed annular ring slot antenna with multiband multimode characteristics is proposed in this communication. The antenna consists of an SIW cavity and an annular slot on top surface as the radiator. Two patch-like radiation patterns and one monopolar radiation pattern at three different frequencies are excited by the single fed antenna.
