Design and Assembly of an Antenna Demonstration System [Education Column]

This paper describes the design, assembly, and operation of a self-contained wireless demonstration system that required only dc power supplies. The system demonstrated polarization effects, radiation patterns, gain, directivity, and signal interference from environmental barriers for dipole, corner reflector (simulated antenna array), Quagi, and embedded patch antennas. The system included an RF oscillator, high-frequency amplifiers, RF bandpass filters, a signal-strength indicator, and multiple adjustable antenna-mounting platforms.
