Abstract :
A novel design of an active antenna with a dielectric resonator stabilized HEMT (high electron mobility transistor) oscillator (DRO) and an aperture-coupled patch antenna is reported. The circuit is fabricated using a coplanar waveguide (CPW) with the oscillator and the antenna on opposite sides of the substrate. The active antenna was demonstrated at 7.6 GHz; however, the design can be scaled to higher frequencies. Excellent oscillator characteristics and radiation patterns have been obtained.<>
