Hybrid dielectric resonator integrated pyramidal horn antenna
Microwave and Optical Technology Letters, 2013AbstractThis article presents the design, simulation, and fabrication of hybrid dielectric resonator integrated pyramidal horn antenna (HDRIPHA) operating from frequency range of 10–18 GHz to cover most of the existing Ku‐band microwave frequencies. The designed HDRIPHA is analyzed and optimized using power modeling software CST Microwave Studio ®. The

Simulating Microwave Radiation of Pyramidal Horn Antenna for Plasma Diagnostics
Communications in Computational Physics, 2006Computational simulation of the radiating structure of a microwave from a pyramidal horn has been successfully accomplished. This simulation capability is developed for plasma diagnostics based on a combination of three-dimensional Maxwell equations in the time domain and the generalized Ohm's law. The transverse electrical electromagnetic wave

Design of hollow dielectric pyramidal horn antennas
IEEE Antennas and Propagation Society International Symposium 1997. Digest, 2002Over the years much research work has been carried out on dielectric-loaded horns of different geometries to obtain high efficiency, low crosspolarisation, low side lobe levels, enhanced bandwidth and pattern shaping capabilities by controlling the amplitude and phase distributions over the aperture.

An optimized quad-ridged horn antenna with pyramidal sidewalls
Journal of Electromagnetic Waves and Applications, 2013The wideband gain and voltage standing wave ratio (VSWR) performance of quad-ridged horn antennas in general are restricted due to the excitation of higher order modes in the coaxial to quad-ridged waveguide transition. This results in large gain variations vs. frequency and break-up of the radiation patterns at higher frequencies.

Predicting directivity of standard-gain pyramidal-horn antennas
IEEE Antennas and Propagation Magazine, 2004Improvements proposed over the years in the edge-diffraction model for a pyramidal-horn antenna have been extended to include the three-dimensional nature of the pyramidal horn in evaluating the edge-diffraction fields. The theoretical model was compared with measured results, measured over a number of years at an international standards laboratory for

A GTD study of pyramidal horns for offset reflector antenna applications
IEEE Transactions on Antennas and Propagation, 1983An efficient computational method is demonstrated for determining the far-field patterns of reflectors illuminated by pyramidal horns. A uniform geometrical theory of diffraction (GTD) formulation is used to determine the near- and far-fields of the horn.

Analysis for phase center of Pyramidal horn antennas for out of band
Proceedings of the 9th International Symposium on Antennas, Propagation and EM Theory, 2010The idea of this paper roots in the electromagnetic compatibility design of the whole aircraft system, in which out of band characteristics of airborne antennas are of equal importance as their characteristics in band. The definition of antenna characteristics for out of band is interpreted. Pyramidal horn antennas are the main research objects in this

Measurements of Selective Near-In Sidelobe Reduction of a Pyramidal, Horn-Reflector Antenna
Bell System Technical Journal, 1983This paper describes measurements of a simple but effective means for reducing selective near-in sidelobe levels of a pyramidal horn-reflector antenna by using microwave absorber to modify the electric field across the reflector surface of the horn-reflector antenna.

A Dual-Band Dual-Circularly Polarized Pyramidal Horn Antenna
2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting, 2019A polarizer system based on a cross slot on the broad-wall of a rectangular waveguide is presented. The system can exhibit dual-bands of operation, one at 72 GHz and one at 84 GHz. The polarizer feeds a pyramidal horn antenna with constant gain of 18 dB.

Three-Dimensional Radiation Characteristics of a Pyramidal Horn-Reflector Antenna
Bell System Technical Journal, 1981A widely used Bell System pyramidal horn-reflector antenna, used in terrestrial radio relay systems, has been characterized over all space. We give the dB contours for principal (as opposed to cross-polarized) measured radiation patterns and compare them to contours of calculated patterns for this antenna at 4 GHz.
