Convergence of Gaussian - Beam Modes in Corrugated Conical Horns
Gaussian beam-mode expansion with only the fundamental mode does not work properly when the angular region of interest is wide. It is necessary to use higher-order mode for the expansion. A study of the convergence of these higher order modes is presented for the case of a corrugated conical horn. Conclusions about the number of modes necessary for good accuracy are given. © 2005 Wiley Periodic...
متن کاملTime-Frequency Channel Parameterization with Application to Multi-Mode Receivers
There is a trend towards flexible radios which are able to cope with a range of wireless communication standards. For the integrated processing of widely different signals — including single-carrier, multicarrier, and spread-spectrum signals — monolithic baseband receivers need universal formats for the signal representation and channel description. We consider a reconfigurable receiver archite...
متن کاملMapping speed for an array of corrugated horns.
I address the choice of horn diameter for millimeter-wave array receivers with corrugated horns. For maximum point-source mapping speed, in both total power and polarization with typical receiver noise contributions and a close-packed horn array that fills the field of view, the optimum horn diameter is 1.6-1.7Flambda, where F is the focal ratio. A +/-25% change in horn diameter gives <10% degr...
متن کاملMode Expansion in Time Domain for Conical Lines with Angular Medium Inhomogeneity
A new modification of the method of Mode Expansion in Time Domain is proposed for studying transient signals propagation in conical lines (including multi-connected ones) with inhomogeneous and time-dependent medium. The method is based on expanding the fields in spherical coordinate system into series of angular dependent modes with mode amplitudes being governed by a system of coupled evoluti...
متن کاملA C-band broadband ortho-mode transducer for radioastronomy polarimetry
BACKGROUND We describe the design, the construction and performance of a narrow band ortho-mode transducer, currently used in the 5 GHz polarimetric receiver of the Galactic Emission Mapping project. RESULTS The ortho-mode transducer was designed to achieve a high degree of transmission within the 400 MHz of the GEM band around the 5 GHz (4.8-5.2 GHz). It is composed of a circular-to-square w...
