Understanding mechanical tolerances, coaxial design details and connector materials used in cable assemblies helps
produce communications equipment with the lowest levels of passive intermodulation (PIM).
Microstrip filters, planar antennas and other RF structures are solved efficiently using the planar Green's function. Only the stripline or antenna needs to be discretised with this method. Ground planes are treated implicitly by the formulation and do not add to the number of unknowns.
Antennas are increasingly incorporated into the windscreens of automobiles. FEKO has a special formulation to design the antenna and calculate the effect of the vehicle on the radiation pattern of the antenna.
The combination of the integral equation (MoM) and the differential equation (FEM) solvers allows the efficient solution of real world radiation hazard problems e.g. calculating the effect of an antenna's radiation on humans sitting inside a vehicle. SAR is calculated according to international standards.
The combined MoM and the Multi-conductor Transmission Line (MTL) theory enables the analysis of coupling into and radiation from cable harnesses in their real-world environments.
Several extensions and special solvers are used in FEKO for efficient EMC analysis, e.g. adaptive frequency interpolation, cable harness analysis, SAR calculation, low frequency stabilisation, time domain analysis. Applications include shielding and coupling investigations, reverberation chamber design and EMC test environment modelling.
Offering both a MoM and a FEM solver FEKO is well-suited for the full-wave analysis of waveguide structures e.g. Magic-T coupler, slotted waveguide antenna, cavity- and waveguide filters. Port modes are specified or calculated and near-fields and S-parameters are extracted with ease.
This paper discuss the adaptation of the fast multi-probe technology to an existing classical planar near field facility through the manufacturing, installation and test of a partial demonstrator in Thales Alenia in Toulouse.
In this paper we take a closer look at various OFDMA based Broadband Wireless Access (BWA) for Homeland Security (HLS) applications and their implementation. Our primary focus is to understand the capabilities required from these applications and to show how flexibility and controllability of system components can help address these requirements.
The published specifications for leakage current in RF power devices are often a source of concern and confusion for engineers and technicians. This paper examines the real meaning behind the leakage current specifications and offers guidance on properly testing a device for leakage current.
