Abstract :
An active receiving microstrip antenna operating around 10 GHz with au GaAs MESFET as active part of the antenna is presented. With the design proposed here, low-noise active receiving antennas with considerably improved bandwidth can be realized. Simulated and measured results of noise figure and power gain along with the corresponding bandwidth are given in addition to customary antenna parameters. Possibilities for noise figure measurement with this non-insertable device have been investigated and an alternative to known procedures is presented.
