A dual-polarised probe is discussed for planar near-field (NF) antenna measurements with a background. The probe has a low cross-polarisation. Analysis has been revisited recently, results of which are presented. Computational power allows to use Method of Moments (MoM) tools. Bodies of revolution can be handled by a tool like CHAMP. A 3-dimensional MoM analysis has been carried out with the tool...
CPW devices with orthogonal or bended accesses (120° in our case) measurements after VNA calibration with conventional (straight) set of standards may generate additional errors. The design and the characterization of first calibration standards with 120° accesses are proposed. These standards will be used for 2-ports vector network analyzer TRL calibration. This work concerns S-parameters measurements...
As a result of constant technological progress over the last several years a rapidly increasing number of used computers, various types of electronic devices and telecommunications equipment. HPEM impulses are increasingly being used to disrupting or even destroy electronic devices. The article presents a modification of the construction of the reflector antenna of HPEM generator increases the intensity...
Results are presented of planar near-field (NF) antenna measurements at Eindhoven University of Technology (TU=e). The antenna under test (AUT) is an engineering model (EM) of a satellite antenna for European coverage from Geostationary Orbit (GEO). It has a shaped beam with Polarisation isolation to allow frequency reuse in a front-fed reflector configuration. Electrical and mechanical axis are not...
The intensive increase of the number of population in modern cities demands a highly reliable power supply, requiring power distribution systems that will accomplish this challenging task. In order to increase the reliability of consumers supply, the additional power distribution substations are commonly installed, which in time become surrounded by the expanded residential areas. In consequence,...
