Constant radiation characteristics for log-periodic dipole array antennas
(Institute of Electrical and Electronics Engineers, 2014)
Given the correct terminal voltages on each element of a log-periodic dipole array constant radiation characteristics can be achieved for an omni-directional radiation pattern. In this communication it is shown that this ...
Modeling of the radiation pattern of a pair of thin circular-arc dipoles over an infinite ground plane
(Institute of Electrical and Electronics Engineers, 2013)
This communication presents a model of the radiation pattern of two circular-arc dipoles above an infinite perfectly electrically conducting ground plane. A Fourier expansion is used to describe the currents on the wires, ...
Rapid calculation of antenna noise temperature in offset Gregorian reflector systems
(Institute of Electrical and Electronics Engineers, 2015)
Antenna noise temperature calculations of reflector systems is often a slow process and makes direct optimization of the sensitivity of these systems a difficult and time consuming task. This paper presents an improvement ...
Efficient adaptive sampling applied to multivariate, multiple output rational interpolation models, with applications in electromagnetics-based device modelling
(Stellenbosch : Stellenbosch University, 2001-12)
ENGLISH ABSTRACT: A robust and efficient adaptive sampling algorithm for multivariate, multiple output rational interpolation models, based on convergents of Thiele-type branched continued fractions, is presented. A ...
