摘要
In this paper. two irises are orthogonally connected to a slot-ring antenna via short-length slits with each of the slits loaded by a pill diode. This antenna can be switched back and forth between righthand and left-hand circular polarization by turning on/off the pill diodes. The slot ring is excited by a slotline. The confomability of the slotline with all SMA is accomplished by inserting a CPW-to-slotline transition between them. An experimental antenna is built on a low-cost FR4 substrate ill order to validate the design. The antenna's uniplanar architecture and its polarization-diversity property will be very useful ill it:wieless-communication systems. (c) 2005 Wiley Periodicals. Inc.
