Antenna and Array Analysis

Port, surface, and field analysis; embedded pattern, pattern multiplication

Perform port, surface, and field (space around the antenna) analysis of antennas and arrays. 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 catalog to resonate at a particular frequency.

Objects

planeWaveExcitationCreate plane wave excitation environment for antennas, arrays, planar structures or 3-D structures
