1. A broadband antenna, comprising:
- a first substrate;
microstrip feed element being disposed along a first surface of said first substrate;
notch antenna means comprising a second substrate and a metalization portion thereupon, said notch antenna means being positioned orthogonal to said first surface of said first substrate with said metalization portion in direct physical and electrical contact with said microstrip feed element for direct signal transmission therebetween; and
ground means being disposed along a second surface of said first substrate in a substantially opposing relationship to said microstrip feed element and being positioned to provide a ground for said notch antenna means,wherein said broadband antenna generates an E-field in a plane orthogonal to said first substrate and propagating from the end of said notch antenna means.

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.
