Task Description and Goals

The project is aiming to construct the feed antenna pattern measurement system with both amplitude and phase measurement capability, based on vector voltmeter, mechanically-tunable phase-locked Gunn oscillator and diode harmonic mixers. The system static amplitude and phase stability will be characterized to see if it requires any improvement. If progress is smoothed and time is permitted, the scanning system will be introduced and the sample standard gain antenna will be measured. The student may have to design a Labview program to realize the automation of the XYZ scanner and the instruments.

Required Background

Electrical engineering, Physics, and mechanical engineering background student is preferred. The student interested on experiment and laboratory work is strongly encouraged.
