Picosecond Pulse Antenna Techniques.
Abstract
The report contains the results of an investigation into techniques for efficiently radiating and receiving unmodulated waveforms of picosecond duration. In particular, the tradeoffs and design parameters necessary for the design of efficient, highly directive picosecond pulse antennas are investigated, both theoretically and experimentally. The work has been divided into several areas of investigation. The first of these was the development of meaningful terminology applicable to the evaluation of wideband antennas. Concepts such as directive gain, effective aperture, radiation patterns, etc., are critically reviewed and modified to corresponding time domain parameters where necessary. This terminology serves as a useful basis for making quantitative comparisons of antennas. The objective of the second part of this program was to develop methods for measuring these terms. To demonstrate the measurement techniques and their usefulness, extensive data were collected on the TEM horn. Several other types of antennas were studied by measuring or calculating their time domain parameters. The results serve as a basis for comparing the performance of these antennas when used to transmit or receive signals of short duration. (Author)
