Abstract :
The design and performance of a CPW-fed microstrip antenna integrated directly with a FET amplifier are presented. The SWR of the passive antenna is less than 1.6 on a 21% bandwidth. Crosspolarisation levels below 20 dB are measured in both E and H-plane. An extra-gain of 6 dB at 5.25 Giz is obtained by adding the FET amplifier to the passive antenna.
