Patent ID: 8847838

Claim:
A broadband antenna comprising: a body having opposing arms arranged for coupling electromagnetic signals to electronics at each distal end and a medial leg arranged for coupling to radiating signals, the body comprising two waveguide paths; and a horn for transmitting and receiving the radiating signals, the horn coupled to the two waveguide paths and comprising: an upper horn wall; and a lower horn wall, each horn wall comprising a plate with two horn ridges extending from a base of the horn and projecting toward an inner region of the horn; wherein each of the two waveguide paths comprises: a horn waveguide section for coupling the electromagnetic signals to the horn, the horn waveguide section having a rectangular cross-section with ridges extending from the longer walls, a bend waveguide section coupled to the horn waveguide section and arranged for turning the electromagnetic signals from the arms of the body to the medial leg to the body; and a transition waveguide section coupled to the bend waveguide section and arranged for transitioning a cross-sectional shape of the bend waveguide section to a cross-sectional shape of the distal ends of the arms of the body.
