Abstract:
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
