Reflective and transmissive mode monolithic millimeter wave array system and in-line amplifier using same
First Claim
1. An amplifier comprising:
- an ortho-mode feed;
a reflective amplifier array adapted to be illuminated by said feed with an input wavefront with a first polarization and to return thereto an amplified wavefront with a second polarization orthogonal to said first wavefront;
feed means for illuminating said array, said feed means including means for illuminating said array with a spherical wavefront; and
means for converting said spherical wavefront to a planar wavefront, said means for converting including at least one reflective element and first and second mirrors.

Abstract
An amplifier including a monolithic semiconductor substrate and an array disposed on said substrate for coherently receiving and retransmitting electromagnetic energy. The array is implemented with a plurality of cells. Each of the cells includes a dual polarization antenna structure for receiving electromagnetic energy and an amplifier connected thereto. The amplifier may include an ortho-mode feed and a reflective amplifier array adapted to be illuminated by the feed with an input wavefront with a first polarization and to return thereto an amplified wavefront with a second polarization orthogonal to the first wavefront. First and second shaped mirrors may be incorporated for illuminating the array with a planar wavefront and converting the reflected planar wavefront to a spherical wavefront.
