TICRA www.ticra.com provides the industry standard analysis and design software for reflector antennas.  GRASP10 analyzes reflector antennas while POS5 designs shaped beams from either reflectors or phased arrays and combinations of the two structures.

CHAMP analyzes circularly symmetric horn antennas, both smooth and corrugated walls, using mode matching and with its efficient optimization delivers a complete design package for these antennas

DIATOOL uses advanced techniques to probe antenna measurements and show the currents which produce the measured pattern. This provides a tool for accessing the as built performance of antennas.

SNIFT enables probe compensated spherical near-field measurements.

To explore the capabilities of TICRA visit their website www.ticra.com

Training for these software tools can be arranged.

The DOS prompt executable TICIRCLE lists circular polarization components and axial ratio from *.cut output file. It also can generate a new *.cut file with axial ratio as first polarization for use in Post Processor.
