A compact microstrip antenna integrated with an amplifier having an area reduction of 70%, compared to the standard circular microstrip patch antenna, is presented. The antenna also provides an enhanced gain of 10‐dB more than its passive counter part. The measured 2:1 VSWR band width is ∼4% at 790 MHz, which is 2.5 times larger than that of the passive microstrip antenna. © 2004 Wiley Periodicals, Inc.
