Design, analyze, and visualize antenna elements and antenna arrays
Antenna Toolbox™ provides functions and apps for the design, analysis, and visualization of antenna elements and arrays. You can design standalone antennas and build arrays of antennas using either predefined elements with parameterized geometry or arbitrary planar elements.
Antenna Toolbox uses the method of moments (MoM) to compute port properties such as impedance, surface properties such as current and charge distribution, and field properties such as the near-field and far-field radiation pattern. You can visualize antenna geometry and analysis results in 2D and 3D.
You can integrate antennas and arrays into wireless systems and use impedance analysis to design matching networks. Antenna Toolbox provides radiation patterns for simulating beam forming and beam steering algorithms. Gerber files can be generated from your design for manufacturing printed circuit board (PCB) antennas. You can install the antennas on large platforms such as cars or airplanes and analyze the effects of the structure on antenna performance. A site viewer enables you to visualize antenna coverage on a 3D terrain map using a variety of propagation models.
Design and visualize antennas using a catalog of parameterized elements including different types of dipole, monopole, patch, spiral, fractal, and horn antennas, among others. Add backing structures such as reflectors or cavities and specify dielectric substrates.
Antenna Designer App
Rapidly choose and design an antenna that fulfills your specifications. Refine, analyze, and visualize the antenna’s performance in a few steps, and iterate until the results match your requirements.
Design antenna arrays by choosing antennas from the catalog or defining custom elements. Use multiple instances of the same antenna element or define a heterogenous array.
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 via multiport S-parameters matrices.
Printed Circuit Board (PCB) Antennas
Design arbitrary planar (2D and 2.5D) antennas and arrays. Combine geometric shapes to define the boundary of the antenna, add multiple dielectric layers, insert vias to connect metal layers, and specify probe or inset feed points.
Gerber File Generation
Generate and visualize Gerber files for PCB antenna fabrication. Select the connectors and choose the manufacturing service to rapidly prototype your PCB antenna.
Approximate large arrays with an infinite number of elements. Analyze infinite arrays over a range of scan angles and calculate scan element patterns. Approximate large installation platforms and backing structures with an infinite ground plane.
Antenna Installation on Platforms
Install antennas and antenna arrays on platforms such as cars, airplanes, or ships. Analyze the effect of the large structure on the antenna performance using physical optics in conjunction with the method of moments.
Evaluate antenna sites for transmitters and receivers, plot communication links, and visualize coverage and signal strength. Use 3D interactive geographical maps to analyze different scenarios for radar and base station positioning.
RF Propagation Models
Compute coverage and communication link properties using propagation models for free space and weather effects. Account for earth diffraction and reflection using Longley-Rice or TIREM™ (Terrain Integrated Rough Earth Model) propagation models.
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.
Method of Moments
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.
Use local and global optimization methods for multiple design variables to improve the performance of your antenna. Speed up the optimization by using parallel computing and machine learning techniques such as surrogate models.
Benchmarking and Verification
Use Antenna Toolbox to compare analysis results with antenna measurements or with state-of-the-art scientific articles.
Tuning and Matching Antennas
Tune the resonance frequency and bandwidth of your antenna by inserting lumped elements on its surface. Use the impedance and S-parameters of antennas and antenna arrays in the design of matching networks using RF Toolbox™.
MIMO System Simulation
Develop beam forming and beam steering algorithms using the complex radiation patterns of antenna elements embedded within an array. Estimate coupling between antenna elements, account for edge effects, and simulate channel performance while accounting for antenna correlation.
