Paris, September 8, 2015, CST® - Computer Simulation Technology AG (CST) will unveil its Characteristic Mode Analysis tool for CST STUDIO SUITE® 2016 at European Microwave Week (EuMW) 2015, booth 311.
Antenna engineers, in particular in the mobile communications industry, are faced with the challenge of optimizing antenna performance while complying with the functional and geometrical constraints of integrating multi-band antennas into compact devices. These engineers’ tasks can be simplified with the latest extension to the CST STUDIO SUITE integral equation solver, the Characteristic Mode Analysis (CMA) tool. CMA is a technique developed to provide physical insight into the behavior of a conducting surface. CMA calculates a set of orthogonal current-modes which are supported on a conducting surface – for example, the current modes of a metal plate. By using CMA, engineers can tune an antenna to the correct resonant frequencies and work out where to place the feed to couple into a particular radiating mode.
