Abstract:
1. A broadband antenna, comprising: a first antenna element having first and second ends spaced apart by a surface thereof; a second antenna element that is substantially co-planar with the first antenna element, the second antenna element having first and second ends spaced apart by a surface thereof, the first end of the second antenna element being spaced apart from the second end of the first antenna element by a first air gap; wherein the first antenna element and the second antenna element comprise substantially flat coplanar sheets of electrically conductive material separated by the first air gap; a conductive structure spaced apart from the first end of the first antenna element by a second air gap, the conductive structure being configured to provide for structural excitation of the antenna over a lower frequency range of an available broadband antenna bandwidth; a feed structure comprising: a conductive tube attached to and extending from the first end of the first antenna element, the second feed path passing through an interior of the conductive tube.
