Abstract

The National Institute of Standards and Technology has developed several ultra-wideband, TEM Horn antennas with phase linearity, short impulse duration, and a near constant antenna factor. These are time-domain antennas used to measure impulsive fields with minimal distortion. This combination of characteristics make this an ideal horn for separating events in the time domain thus obtaining an accurate frequency response from nearby scattering objects or to represent complicated antenna patterns or frequency outputs from sources. This report describes the development of each antenna, their characteristics, numerical modeling applied to each antenna to study various aspects of design, and various measurement applications of these antennas. These applications include site attenuation measurements, chamber evaluations, radar imaging studies, and aircraft shielding evaluations. This report is intended for those who wish to build or use the technology developed at NIST.
