Import, Export, and Visualization

Read, visualize, and write STL files and MSI planet antenna files, import or measure pattern data in 2-D and 3-D, reconstruct 3-D pattern from 2-D slices, create interactive polar plots

MSI planet antenna files contain antenna radiation patterns in ASCII text format. Using Antenna Toolbox™ functions, you can read and write data from MSI planet antenna files. You can also extract antenna data from CSV files and plot the radiation patterns and EM fields. You can reconstruct a 3-D radiation pattern from 2-D orthogonal pattern slices data using AI based method. You can import measured pattern data of an antenna and use it for applications involving reflector antennas. To learn how to read, visualize, and write data from MSI planet antenna files see Read, Visualize and Write MSI Planet Antenna Files.
