A TEM-Horn Antenna with Dielectric Lens for Fast Impulse Response

  • John F. Aurand

Abstract

We recently designed and built a TEM-horn antenna with a dielectric aperture lens in order to achieve faster transient pulse response. TEM (transverse electromagnetic) horns are commonly used for wideband time-domain work because they offer minimum dispersion as a traveling-wave endfire structure (which can be made fairly nonresonant). However, even carefully designed TEM horns have an inherent pulse-smearing geometrical effect due to spherical wavefront propagation within the structure. A dielectric planar-convex aperture lens is used to accomplish this plane-wave to spherical-wave conversion, by collimating the wavefront between the plates in order to improve the impulse response.
