Compact microstrip meander antenna

Abstract

An electrically small microstrip meander antenna incorporating the folded technology is fabricated and experimental results ale presented in this paper. This antenna has the advantages 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 variation of the return loss can be easily tuned by changing the feeding points and the microstrip-line length. The maximum measured bandwidth is approximately 770 MHz (12.6% operational bandwidth around 6.115 GHz) when the middle feeding point is chosen. (C) 1999 John Wiley & Sons, Inc.
