Uni-Planar Folded Meander Line Slot Antenna With Short Circuit

We present a thin, uni-planar printed antenna that is electrically small and has a near omnidirectional radiation pattern. The antenna is based on a folded meander line slot radiator and uses a short circuit near the feed location to provide a good impedance match at the frequency of operation. The low cost antenna has a 10 dB return loss bandwidth of approximately 5% and a gain of near 0 dBi
