PHASED ARRAY ANTENNA FEED COMBINER

Abstract: described herein are feed networks for phased array antennas. an exemplary feed combiner assembly for a phased array antenna can electrically combine multiple radiating elements in a column for connection to a common feed line of a feed network. this enables transmission of a signal to the multiple radiating elements with a single feed line, reducing the number of feed lines required for feeding the radiating elements. the feed combiner assembly can provide for a more compact feed network and easier replacement than a conventional feed line connection configuration. each radiating element of the phased array antenna can have a capacitive coupling portion that capacitively couples the radiating element to adjacent radiating elements. the spacing between adjacent radiating elements can be controlled by a non-conductive, overmolded spacer disposed on the capacitive coupling portion, which aligns and maintains a minimum separation between adjacent radiating elements.
