Pattern Data Integration and Visualization
Import measured or third-party simulated radiation pattern data of an
antenna or array from TXT, CSV, FFD, or MSI Planet antenna file
(.msi or .pln). Use this data to
excite cavity and reflector backing structures through the measuredAntenna object or integrate it into RF systems using
the Antenna (RF Blockset) block. Visualize 3-D radiation patterns, near- and
far-fields, and create interactive polar plots with this data. Antenna
Toolbox™ functions allow you to read and write radiation pattern data from
MSI planet antenna files in ASCII text format. Additionally, you can
reconstruct a 3-D radiation pattern from 2-D pattern slice data.

Featured Examples
Read, Visualize and Write MSI Planet Antenna Files
Read an MSI Planet antenna file (.msi or .pln). You can read an MSI file using the msiread function and visualize the data using the polarpattern function. You can also write the data back into the MSI Planet format using the msiwrite function.
Import Measured Field Data and Visualize Radiation Pattern
Visualize a radiation pattern and vector fields from the imported pattern data. Use the patternCustom function to plot the field data in 3D. This function also allows you to view the sliced data. Alternatively, use the polarpattern object to visualize the field data in 2D polar format. The polarpattern function allows you to interact with the data and perform antenna specific measurements. You can also plot the vector fields at a point in space using the fieldsCustom function.
Reconstruction of 3-D Radiation Pattern from 2-D Orthogonal Slices
Reconstruct a 3-D radiation pattern using patternFromSlices function. A 3-D radiation pattern is a very important tool for antenna analysis, characterization, design, planning, and applications. This example shows reconstruction of 3-D radiation pattern from two orthogonal slices for an omni-directional dipole, a directional helix, and imported pattern data of an antenna.
Reconstruct 3-D Antenna Pattern from 2-D Slices Using Deep Learning
Use deep learning to reconstruct a 3-D antenna radiation pattern from two orthogonal 2-D slices.
