Study of a wideband sinuous feed for reflector antenna applications
(Stellenbosch : Stellenbosch University, 2013-12)
ENGLISH ABSTRACT: This thesis presents a thorough study of the printed sinuous antenna and its characterisation as a feed for re ector antenna applications. Two di erent techniques are used in this study, namely a ...
Parametric modeling of radiation patterns and scattering parameters of antennas
(Institute of Electrical and Electronics Engineers, 2016)
This paper describes a data-driven method to model the radiation patterns (over a large angular region) and scattering parameters of antennas as a function of the geometry of the antenna. The radiation pattern model consists ...
Modelling of Antenna Responses
(Stellenbosch : Stellenbosch University, 2016-12)
ENGLISH ABSTRACT: This dissertation presents surrogate modelling techniques for the radiation patterns and scattering parameters of antennas. The models are developed in the context of calibration of re ector antennas ...
Multivariate adaptive sampling of parameterized antenna responses
(Institute of Electrical and Electronics Engineers, 2017)
ENGLISH ABSTRACT: We present a robust method to adaptively construct parameterized models of the full radiation patterns of antennas and the associated S-parameters. The method sequentially selects points (geometric ...
