Abstract:

The electronic scanning antenna array has many advantages over the conventional antenna system. This thesis proposes the marriage of a low noise tunnel diode amplifier and varactor phase shifter at the antenna to scan and amplify. A different method of tuning varactor phase shifters is proposed, along with a simple method of designing tunnel diode amplifiers using the Smith Chart for determining design parameters. The final design consists of a two element sample array using four tunnel diodes and two varactors in a strip-line circuit directly behind an S-band spiral antenna. Author
