Antenna Solution new


The SEMCAD X Matterhorn ANTENNA software package is a full-wave 3D finite-difference time-domain (FDTD) simulation solution for solving all electromagnetic (EM) propagation and radiation challenges. The intuitive design flow allows for the efficient and rapid design and optimization of antenna systems and large radiating structures.

The ANTENNA software package, the solvers most frequently applied in near-field dosimetry, have been extensively validated and documented according to the IEEE/IEC 62704-1 standard as well as by comparisons with measured data (>200 publications). Comprehensive documentation for SEMCAD X Matterhorn is available.

SEMCAD X Matterhorn provides integrated, advanced, and interactive computer-aided design (CAD) modeling without the need for a preprocessor or live-link, and can handle the most complex CAD-based models.

Processing (interpolation, interactive cropping/masking, etc.) and visualization of the simulation results is performed together with the measured/ imaging data directly on the models.
