ANTENNA FEED MODULE

摘要

A feed module (100) is provided for an array antenna (220). The feed module comprises a multi-layer printed circuit board (PCB) feed structure for coupling signals between connections to transmitters or receivers and connection points (120) for connecting to antenna elements (225) of the array antenna (220). The multi-layer PCB feed structure comprises a body portion (110), incorporating coupling components (400,405; 500,505), and a number of line sections for connecting to elements of the array antenna. The planar layers of the multi-layer PCB are arranged to be mounted substantially perpendicular to a planar array (220) of antenna elements of the array antenna when the feed module (100) is integrated therewith.
