Optenni Lab: Calculation of radiation efficiency

Optenni Lab calculates the antenna radiation efficiency from the impedance and measured total efficiency data, which do not have to use the same frequency grid.

The impedance (S-parameter) data is read from a Touchstone file and the radiation efficiency data is read from a text file where possible comment rows will be ignored and the data can be specified using different frequency units (e.g. MHz or GHz) and either in linear of dB scale. The coupling to other antenna ports will be taken into account in the calculation of the radiation efficiency.

In addition, when a matching circuit has been constructed, Optenni Lab calculates the total efficiency through the circuit, taking into account impedance mismatch, losses in the matching circuit, the radiation efficiency and coupling to the other antennas.
