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.
