finds exact gain, directivity and input impedance of Yagi or log-periodic antennas (planar symmetric array of cylindrical dipoles, many driven elements) for a range of specified frequencies, integrates 2D for segments on the same element, moment method

MedFDTD is a 3D parallel electromagnetic simulation software for bioelectromagnetics by FDTD method. MedFDTD can simulate electromagnetic radiation, calculate SAR and temperature rise, estimate antenna radiation power, and all calculations can be performed in parallel.

The existing 2D ITU generic channel model is enhanced to account for 3D component, different operating frequency bands. The enhanced version have LSPs statistics from 3D ray tracer engine developed by University of Bristol, CSN group.

PySNF (which stands for Python Spherical Near-Field) is an open source spherical near-field to far-field module written in Python. With PySNF, users can calculate probe-corrected far-field radiation patterns from spherical near-field antenna measurements. In addition, spherical wave coefficients from simulated or measured antenna radiation patterns can be obtained. The vast majority of the code in this module was developed using equations presented in the book Spherical Near-Field Antenna Measurements, edited by J.E. Hansen.

This program is a graphical visualization of various engineering concepts like - - Antenna Radiation patterns (3D full & sectional views) - Electron Bunching in a 2 cavity Klystron amplifier - many more

Enhanced Machine Controller-based Antenna Range (EMCAR) EMCAR employs LinuxCNC based machine control (linuxcnc.org) coupled with open source software to implement a measurement system for antenna radiation pattern data (i.e. an antenna range).

Antenna Radiation Diagram Plotter - Polar plots of measured EM emission, with a proper radial axis scaling and span. Three source files (plain text) can be loaded and plotted at the same time. Export to file or clipboard.

Lunessaphir Mini Beam Simulator is a simulator of antenna propagation.You can see easily the spacial radiation patterns of array antenna like a thermogram, depending on amplification and phase of each antenna element.
