Abstract :
Presents a 60 GHz-band active microstrip patch antenna using a Gunn diode as an oscillator in a reflection amplifier configuration. The oscillator consists of a patch antenna, a matching and bias circuit and an Alpha Industries DGB8266 packaged Gunn diode. 9.26 mW is obtained at 63.24 GHz. A tuning bandwidth of 1 GHz is attained by varying the DC bias voltage. The radiation patterns agree well with the theory and low level crosspolarisation patterns are achieved over a broad bandwidth
