Antenna Toolbox

MAJOR UPDATE

 

Antenna Toolbox

Design, analyze, and visualize antenna elements and antenna arrays

Diagram of various antenna categories and array layouts, including cavity, cloverleaf, dipole, circularArray, and eggCrate, with illustrative icons.

Antenna and Array Modeling

Interactively design antennas using the Antenna Designer app with over 100 parameterized elements (including dipoles, patches, and horns), add backing structures, and specify material properties. Model arrays in various layouts with mutual coupling. Perform infinite array analysis for modeling large antennas.

Analysis, Benchmarking, and Verification

Analyze antenna elements and arrays using the full-wave 3D method of moments (MoM) solver. Compute port properties such as impedance, S-parameters, current and charge distribution, and near- and far-field radiation patterns. Compare analysis results with antenna measurements.

3D Modeling with CAD Files

Create custom planar and 3D structures, define feed points, and create antenna designs using shapes or CAD files. Attach connectors to PCB antennas, customize PCB file generation for specific manufacturing services, and generate Gerber files for fabrication.

AI and Optimization

Analyze and optimize antenna designs with AI-powered models. Use 3D pattern reconstruction from 2D slices with deep learning and AI-driven optimizers (SADEA and TR-SADEA) to reduce simulation time and meet design objectives.

Integrating and Visualizing Pattern Data

Import measured or simulated radiation pattern data from text, CSV, or MSI Planet antenna files (.MSI or. PLN) to excite backing structures or integrate pattern data into RF systems. Visualize far- and near-field data with 3D or polar plots. Use antenna impedance and S-parameters to design matching networks (with RF Toolbox), and design distributed matching networks (with RF PCB Toolbox).

Antenna Installation and Large Structure Analysis

Install antennas and antenna arrays on platforms such as cars, airplanes, or ships. Determine the radar cross section (RCS) of large objects for accurate target detection. Analyze large structures and their effects on antenna arrays using physical optics (PO), MoM-PO, or fast multipole method (FMM) solvers.

RF Propagation Models

Compute coverage and communication link properties using 3D geographical maps. Account for earth diffraction and reflection using Longley-Rice or Terrain Integrated Rough Earth Model™ (TIREM™) propagation models. Evaluate coverage in urban scenarios using ray tracing propagation models.
