Abstract
A microwave antenna for an aircraft including a reflector element with a front surface and a rear surface. A horn is mounted to the front surface of the reflector element and an orthomode transducer is mounted to the rear surface of the reflector element. The orthomode transducer is coupled to the horn. Solid state power amplifiers that amplify a microwave signal to be transmitted and low noise amplifiers that amplify a received microwave signal are coupled to the orthomode transducer. The solid state amplifiers and the low noise amplifiers are also located on the rear surface of the reflector element.
