Impedance matching/power splitting network for a multi-element antenna array

A device for impedance matching a signal generator to a plurality of elements of a multi-element load. The device includes an outer conductor having an inner surface and an inner conductor positioned within the outer conductor, and having an outer surface. The device further includes a first and second set of transformation sections, which provide a particular separation distance between the inner surface of the outer conductor and the outer surface of the inner conductor to yield a particular characteristic impedance for each of the first and second sets of transformation sections, thereby substantially matching the impedance of the generator to the elements of the load.
