ESTEAM by TICRA offers advanced modeling and simulation of antennas mounted on large or complex structures. Users can create parameterized objects or import detailed CAD models, supporting realistic analysis of antenna performance in challenging environments. When integrated with TICRA’s GRASP tool, ESTEAM enables precise design and optimization of reflector and multi-antenna systems.
Based on special higher-order basis functions, ESTEAM is the most powerful full-wave solver on the market.
To handle electrically very large problems, ESTEAM is enhanced with an advanced Multi-Level Fast-Multipole Method (MLFMM) implementation.
Use built-in geometry shapes, including wires, boxes, BoR, and clusters of any of these, as well as imported CAD files to define antenna systems.
This use case shows how GRASP and ESTEAM predict the impact of a CubeSat chassis on a compact reflector antenna’s performance. Modeling reveals increased sidelobes, cross-polarization, and a >1 dB reduction in peak directivity, supporting reliable CubeSat antenna design.
