ABSTRACT:
A broadband antenna capable of transmitting or receiving radio frequency signals. The antenna includes a substrate having a surface upon which a microstrip feed element is positioned orthogonal to the substrate, and a portion of the antenna element is positioned on and in direct contact with a portion of the microstrip feed element for transmitting or receiving signals therebetween. A ground plane is disposed on a surface of the substrate which is in opposing relation to and spaced from the microstrip feed element. Additionally, the antenna element includes a tapered notch of a "Vivaldi" configuration which facilitates endfire operation and reduces beamwidth.
