Compact microstrip meander antenna

An electrically small microstrip meander antenna incorporating the folded t echnology is fabricated and experimental results ale presented in this pape r. This antenna has the advantages of compact size, ease of manufacturing, broad bandwidth, and multiband characteristics. Different-feed and differen t-length antennas are tested. Techniques to reduce the antenna size are pre sented, and performance trends are established. The measured results show t hat the variation of the return loss can be easily tuned by changing the fe eding points and the microstrip-line length. The maximum measured bandwidth is approximately 770 MHz (12.6% operational bandwidth around 6.115 GHz) wh en the middle feeding point is chosen. (C) 1999 John Wiley & Sons, Inc.
