Abstract: A compact, single feed, multi frequency design of reconfigurable microstrip antenna with various slots are presented in this paper. A rectangular patch loaded with horizontal slots having extended slot arms constitutes the fundamental structure of the antenna. The tuning of the multi resonant frequencies is realized by varying the effective electrical length of the slots by loading varactor diodes across the slots. A size reduction of 84% for the lower operating frequency is obtained when compared to conventional rectangular microstrip patch. Proposed antennas are useful for multi-band wireless applications like GSM1800, IMT2000, WLAN etc operating over a wide range of bands. Measured and simulated results of return loss, antenna gain and radiation patterns are also discussed.

Keywords: single feed, multi frequency, WLAN, rectangular patch, return loss.
