Abstract

See full text

A new class of feed horns is provided based on the use of metamaterial printed circuit board (PCB) liners on the walls of the feed horns. These feed horns may be implemented to achieve low cost operation. PCBs making up the metamaterial liner may be assembled together in such a manner as to form a feed horn with a square or rectangular aperture shape, although other suitable shapes are possible. These PCBs may be fabricated from standard low cost, off-the-shelf dielectric material. A conductor artwork pattern on the PCB surface forming the interior surface of the feed horn can be designed such that the PCB feed horn yields radio frequency (RF) properties similar to that of a corrugated feed horn. A simple flat plate ground plane bonded to the back side of the PCB can serve as the feed horn structure.
