Modularized multiple-feed electromagnetic signal receiving apparatus

摘要

This invention is a compact and cost effective multiple-feed signal receiver for use in conjunction with a parabolic dish antenna to receive electromagnetic signals from more than one satellite clusters. The multiple-feed signal receiver has a multi-layer structure to integrate circuit boards for different frequency bands or the same frequency band for different signal processing within a limited cross-section and to isolate these boards from signal interference with one another.
