cross polarization measurement

Dear all,

I am working on my final assignment in microstrip antenna research. I need some tutorials about cross polarization measurements especially for microstrip antennas.

Thanks

If your measurements are of a linear antenna just rotate the source 90 degrees (roll plane) and repeat the measurement. You will have the cross polarized response (vs. matched polarization).

If your measurement is if a circularly polarized antenna use a source with the opposite sense circular polarization.
