Efficiency of a Linear Polarisation Antenna

[petrus999]

If i know the total efficiency of a linear polarised antenna. Is it possible to calculate how much of the Efficiency comes from RHCP and LHCP using the axial ratio or maybe another method

Hi, Petrus:

I don't think there is a simple formua for it. Efficiency is related to the total radiated power and it is the result of an integral of all the field at all the angles. Axial ratio is defined at some particular (theta, phi) angle. It is not a one to one mapping. In the other word, you may have many different kinds of patterns with the same radiation efficiency. Regards.
