摘要：
A 360 degrees retrodirective self-oscillating mixer (SOM) array Is presented. The structure is composed of a 96-element transistor grid conformed around a cylindrical dielectric core. The three-dimensional architecture allows for retrodirectivity over a larger range of incident angles compared to planar retrodirective arrays. Use of the SOM's free-running oscillation signal eliminates the need for an external LO. Experimental results at C-band confirm retrodirectivity of source beams incident at angles of 0 degrees, 20 degrees, -25 degrees and -160 degrees in the H-plane.
