XPD has various meanings in the Technology category. Discover the full forms, definitions, and usage contexts of XPD in Technology.
The ratio of the signal power received (or transmitted) by an antenna on one polarisation (the polarisation of the desired signal) to the signal power received (transmitted) on the opposite polarisation. This ratio is usually expressed in decibels. It is a measure of the ability of the antenna to detect (emit) signals on one polarisation and to reject signals at the same frequency having the opposite polarisation.
