EM Software and System GmbH's new FEKO Suite 5.5 includes significant new features and extensions like efficient modelling of windscreen antennas, Periodic Boundary Conditions for both metals and dielectrics e.g. patch antenna arrays, Modal Port Boundary Conditions using the FEM and the use of GO for both dielectrics and metals. Its automatic snapping features as well as its alignment tools to place objects (e.g. placing antennas imported to FEKO from Antenna Magus) on structures makes geometry construction very easy. The MLFMM approach has also been enhanced and accelerated. New fully automatic update mechanisms now keep downloads to a minimum.
