About AToM

The AToM (Antenna Toolbox for MATLAB) is written entirely in MATLAB, so the user will enjoy its semi-open architecture and friendly operation through GUI or direct access to low level functions. Main simulation core is based on Method of moments, both for 3D wire and planar structures. Together with modal decomposition (Characteristic modes), the source concept, feeding synthesis and powerful optimization (FOPS optimizer), it will present unique tool for analysis and synthesis of (small) antennas. Full list of AToM features is available below.

AToM Features


AToM Design Viewer with a capacitive loop antenna and active pick-point tool. The PEC symmetric plane is enabled and highlighted by green color.

AToM DesignViewer

Draw the antenna interactively, visualize mesh grid, feeding scenarios, and boundary conditions. Take the advantage of AToM Workspace.


List of user-defined AToM variables which parametrize the capacitive loop antenna.

AToM Workspace

Create own variables and use them freely throughout the AToM to parametrize all your models. AToM Workspace is the primary gateway between variables in MATLAB workspace and AToM.


Record of AToM History for capacitive loop antenna.

AToM History

Rely on automatic MATLAB-executable record of your AToM session. Modify it, send it, share it.


A segment of MATLAB code with AToM-executable commands (start of MoM solver and acquisition of the results).

AToM Syntax

Have a full control of the AToM workflow. Access all powerful low-level functions and features. Combine freely AToM commands and other MATLAB commands.


Complex fractal body discretized using local density function (discretization is finer where high amplitudes of current density are expected).

Advanced Mesher

Use fast and versatile AToM mesher. Set up local density functions. Enjoy various settings of uniform mesh grid and full support of symmetries.
