Compact microstrip meander antenna

An electrically small microstrip meander antenna incorporating the folded technology is fabricated and experimental results are presented in this paper. This antenna has the ad antages of compact size, ease of manufacturing, broad bandwidth, and multiband characteristics. Different-feed and different-length antennas are tested. Techniques to reduce the antenna size are presented, and performance trends are established. The measured results show that the ariation of the return loss can be easily tuned by changing the feeding points and the microstrip-line length. The maximum measured bandwidth is approxi( ) mately 770 MHz 12.6% operational bandwidth around 6.115 GHz when the middle feeding point is chosen. Q 1999 John Wiley & Sons, Inc.
