Abstract
A multiband antenna feed, an antenna incorporating the multiband antenna feed and a method are disclosed. An apparatus, comprises: a first port which may be configured to convey a first signal at a first frequency. A second port may configured to convey a second signal at a second frequency. The second frequency may be higher than the first frequency. A third port may be configured to convey the first signal and the second signal with a feed for a multiband antenna. The third port may have an inner waveguide and a coaxial waveguide. A first network may couple the first port with the coaxial waveguide and may be configured to propagate the first signal between the first port and the coaxial waveguide. A second network may couple the second port with the inner waveguide and may be configured to propagate the second signal between the second port and the inner waveguide.
