Horn Image Guide Leaky-Wave Antenna
MTT-S International Microwave Symposium Digest, 1981A novel approach for designing a frequency-scanning millimeter-wave antenna is described. The antenna is constructed by using an image wide leaky-wave antenna embedded in a long trough with metal flares along both sides. The optimum flare angle for achieving maximum gain is theoretically predicted.

Shaped-beam horn-reflector antennas
IEEE Transactions on Antennas and Propagation, 1975A design method for a horn-reflector antenna, which has a beam of arbitrary cross section, is developed. To show the effectiveness of the design theory, the measured data of an electrical model of Japan's domestic communications satellite antenna of this type are shown in comparison with calculated results.

Simulated corrugated feed horn antenna
International Symposium on Antennas and Propagation Society, Merging Technologies for the 90's, 1990A technique for developing a new type of feed horn with the same radiation characteristics as a metallic corrugated horn is presented. This horn antenna with low back and sidelobe levels can be used as a substitute for a metallic corrugated horn with added advantages of high gain, low cross polarization, low cost, and light weight.

Proceedings of the IRE, 1953
Formulas are derived for the E- and H-plane radiation patterns of antennas fed by horns as functions of illumination taper. The case of a single lens or reflector antenna fed by two contiguous horns stacked in either one of the principal planes is then investigated.

Single aperture monopulse horn antenna
IEEE Microwave and Wireless Components Letters, 2005This paper describes the design and performance of a conical Potter horn antenna which can generate sum or difference far field patterns suitable for monopulse tracking applications. The antenna consists of a horn antenna fed with a metal post loaded polarizer which is energised by suitably phased 50-/spl Omega/ matched coaxial probes.

In this work the basic theory of circular corrugated horn antennas is presented, using easy concepts with simple mathematics. The aim is to give the reader an understanding of the fundamental electromagnetic properties of these devices and to provide a set of quantitative design tools for the electromagnetic engineer.

Validated Antenna Models for Standard Gain Horn Antennas
2009Abstract : Developed radiation pattern models of standard gain horn antennas using High Frequency Structure Simulator (HFSS) software are presented in this technical note. The models were validated using data measured in an anechoic chamber. Comparison tables of the beamwidth, sidelobe level and first null beamwidth of the measured and modeled ...

An SIW Horn Antenna With Flat-Top Beam for Millimeter-Wave Applications
IEEE Antennas and Wireless Propagation LettersIn this letter, a flat-top beam (FTB) antenna realized by a substrate-integrated waveguide (SIW) H-plane horn is presented for millimeter-wave applications. Its FTB is formed by manipulating electromagnetic fields on its radiating aperture.

High Voltage UWB Horn Antennas
1997Antenna structures capable of supporting (essentially) transverse electromagnetic (TEM) spherical waves are characterised by their frequency independence over a wide band width, making them ideal candidates for transient field radiation. In particular the triangular plate configuration of the TEM horn is of interest for a variety of directive wide-band
