Antenna Toolbox

Design, analyze, and visualize antenna elements and antenna arrays

Get Started:

Antenna and Array Design

Rapidly design antennas and arrays starting from a catalog of parameterized elements or using dedicated apps.

Antenna and Array Catalog

Design and visualize antennas using a catalog of almost 100 parameterized elements including different types of dipole, monopole, patch, spiral, fractal, and horn antennas, among others. Add backing structures such as reflectors or cavities. Specify metal properties and dielectric substrates to estimate losses and efficiency.

Design linear, rectangular, circular, and conformal arrays and compute the effect of mutual coupling. Perform infinite array analysis for modelling large antennas.

Major categories of the antenna catalog and array catalog.

Antenna Designer and Array Designer App

Rapidly choose and design an antenna or an array that fulfills your specifications. Refine, analyze, and visualize the performance in a few steps, and iterate on geometric and material properties until the results match your requirements.

Custom Geometry and Fabrication

Design arbitrary planar antennas or arrays. Import and generate Gerber files for rapid prototyping and fabrication. Create custom 3D antennas from STL files.

Printed Circuit Board (PCB) and Custom 3D Antennas

Design arbitrary planar (2D and 2.5D) antennas and arrays. Import Gerber files or combine geometric shapes to define the boundary of the antenna, add multiple metal and dielectric layers, insert vias, and specify probe or inset feed points. Generate and visualize Gerber files for PCB antenna fabrication. Import and analyze 3D STL files to optimize existing antenna designs or to describe installation platforms.

Platform-Installed Antennas and Large Structure Analysis

Import CAD files describing large structures such as planes, ships, or cars. Install antennas on these platforms to analyze the effect on performance.

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. Approximate large arrays with an infinite number of elements. Analyze infinite arrays over a range of scan angles and calculate scan element patterns.

Tuning and Optimization

Improve antenna bandwidth, build matching networks, and optimize antenna performance using machine learning techniques.

Tuning, Matching, and Antenna Optimization

Tune the resonance frequency and bandwidth of your antenna by connecting lumped elements to its surface. Use the impedance and S-parameters of antennas and antenna arrays in the design of matching networks using RF Toolbox™.

Apply local and global optimization methods for multiple design variables to improve the performance of your antenna. Speed up the optimization using parallel computing and machine learning techniques such as surrogate models.

Analysis and Benchmarking

Analyze antennas with the full-wave 3D method of moments (MoM) and compare results with measurements.

Benchmarking and Verification

Analyze antenna elements and arrays using the full-wave 3D MoM. Compute port properties such as impedance and S-parameters, current and charge distribution, and near- and far-field radiation patterns. Compare analysis results with antenna measurements or with state-of-the-art scientific articles.

Import and Visualize Custom Patterns

Import radiation patterns from MSI Planet antenna files (.MSI or .PLN). Visualize far-field and near-field data using 3D or polar plots. Interactively inspect the data and compute antenna metrics.

RF Propagation and MIMO System Integration

Visualize coverage and communication links on a 3D terrain map. Perform end-to-end simulation of wireless transceivers including antenna arrays.

RF Propagation Models

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

MIMO System Simulation

Determine the correlation matrix between antennas in multiple-input multiple-output (MIMO) systems, study the effect of closely spaced antennas on the radiation pattern of phased array systems, and evaluate electrical coupling.

Develop beamforming and beam steering algorithms using radiation patterns of antenna elements embedded within an array. Simulate antenna arrays in RF front-ends while estimating impedance mismatches, coupling, and non-linear effects.
