Journal ArticleDOI
Design of corrugated horns: a primer
Christophe Granet,G.L. James +1 more
TL;DR: In this paper, the class of circularly symmetrical corrugated horns and the parameters in designing are considered. And some basic information for the inexperienced horn designer to get started in designing their CORRUGATED horn is provided.
Journal ArticleDOI
Diplexing feed assemblies for application to dual-reflector antennas
TL;DR: In this article, the authors investigate possible configurations for dual-band waveguide diplexing assemblies appropriate for use as feed systems for dual reflector antennas, where the bands are well separated and individually have relatively wide bandwidths.
Journal ArticleDOI
Design of wide-band compact corrugated horns
TL;DR: In this paper, a specially profiled corrugated horn with a ring-loaded input converter section is shown to operate over bandwidth ratios of up to 2.4: 1. The cross polarization across the band is relatively low, and the change in beamwidth and phase center position with frequency is acceptable for many applications.
Journal ArticleDOI
The designing, manufacturing, and testing of a dual-band feed system for the Parkes radio telescope
Christophe Granet,Henry Z. Zhang,A.R. Forsyth,G.R. Graves,P. Doherty,K.J. Greene,G.L. James,P. Sykes,Trevor S. Bird,M. W. Sinclair,G. Moorey,R.N. Manchester +11 more
TL;DR: In this paper, a dual-band feed system for the Parkes radio telescope (PRS) was designed and tested in the 648-712 MHz and 2.6-3.6 GHz frequency bands.

A dual-band feed system for the Parkes radio telescope
Christophe Granet,H.Z. Zhang,K.J. Greene,G.L. James,A.R. Forsyth,Trevor S. Bird,R.N. Manchester,M. W. Sinclair,P. Sykes +8 more
TL;DR: In this paper, a dual-band, dual-polarization, coaxial receiver system for 10 cm and 50 cm wavelengths was designed and constructed for the Parkes radio telescope, where the primary motivation is to provide a receiver system optimised for pulsar observations, such as the 9 cm transition of CH and various recombination lines.
