Abstract

This paper presents a 60 GHz-band active microstrip patch antema using a Gunn diode as an oscillator in a reflection amplifier configuration. The oscillator consists of a patch antenna, the matching and bias circuit and an Alpha Industries DGB8266 packaged Gunn diode. 9.26 mW are obtained at 63.24 GHz. A tuning bandwidth of 1 GHz is attained by varying the dc bias voltage. The radiation pattems agree well with the theory and low level cross-polarisation patterns are achieved over a broad bandwidth. The 60 GHz-band is particularly important for micro-cellular mobile communications, and this active antenna is ideally suited for base-station applications in the 62.5/63.5 GHz bands intended for the European Mobile Broadband System (MBS).
