CAPITOLE-RF: Simulation software

This post is also available in: French

the characteristics of your antennas and optimize their placement on a structure


The NEXIO range of simulation software allows to estimate the RF performance of a product during the design phase prior to its realization, but also to estimate the impact of modification on an existing product.

With a modern and intuitive graphical interface, it can be used occasionally by non-specialists in a wide variety of applications and provides fast and accurate results.

CAPITOLE-RF is powered by the latest generation of solvers from the NEXIO innovation cluster.

CAPITOLE-RF can calculate the characteristics of an antenna (gain, impedance, etc.) to optimize its design.

CAPITOLE-RF allows to optimize the placement of antennas on a structure (box, aircraft, vehicle, IOT…).
