In this paper, we demonstrate a new type of power combining array using two-port FET oscillators as the active elements [3]. The oscillators are arranged in a square planar array, with the output of each connected to a patch radiator. The key difference between this approach and the work cited above is that the oscillators are injection locked to a single external source by means of a Wilkinson-type 16 way power divider, rather than by parasitic coupling between the oscillating elements. |
