A broadband antenna capable of transmitting or receiving radio frequency signals. The antenna (16) includes a substrate (18) having a surface upon which a microstrip feed element (30) is positioned orthogonal to the substrate, and a portion of the antenna element (16) is positioned on and in direct contact with a portion of the microstrip feed element (30) for transmitting or receiving signals therebetween. A ground plane (32) is disposed on a surface of the substrate (28) which is in opposing relation to and spaced from the microstrip feed element. Additionally, the antenna element includes a tapered notch (22) of a "Vivaldi" configuration which facilitates endfire operation and reduces beamwidth.
