Abstract :
A new active antenna structure with applications in quasi-optical power combining is described. The active antenna combines a slotline FET oscillator with a notch antenna. The new structure was successfully used to create both E-plane and H-plane linear arrays as well as a 2D array. Preliminary results of radiation patterns and the power combining efficiencies of the arrays are discussed
