Analysis of Switched Wire Antennas

Abstract

The goals of this research project are to create the tools needed to analyze and understand loaded and switched antennas and to design the experimental apparatus needed to verify results obtained from computations. The antennas of interest cover the HF range and must be amenable to frequency hopping modulation schemes. Increase in bandwidth of monopole-like structures may be achieved by means of loading/tuning circuits and incremental bandwidth enhancement may be obtained by electronically switching antenna loads and elements. In this project, monopoles with shielded lumped loads are analyzed and results are confirmed experimentally. Also investigated are the coupling of time-domain signals between two closely spaced monopole antennas and the behavior of a time-domain signal injected at one port of a loaded loop antenna above a ground plane and sampled at the other port.
