Analysis, Design, and Tuning

Port, surface, and field analysis; meshing, external data I/O, embedded pattern, pattern multiplication

Each element in the Antenna Toolbox™ library has a set of analysis functions. Perform port, surface, and field (space around the antenna) analysis of antennas and arrays. Mesh the antennas into discretized triangles for solving analysis equations. Use plane waves to excite an antenna to simulate a receiving antenna. Use Antenna Toolbox functions to read and write data from MSI Planet antenna files. Design and tune geometric properties of antennas in the antenna library to resonate at a particular frequency.
