Patent ID: 6922177

Claim:
An impulse radar antenna array comprising: a. a ground plane, comprising a first surface and a second surface; and b. a plurality of antenna elements affixed to said first surface, each of said plurality of antenna elements being adapted to emit and receive ultra wideband signals; said plurality of antenna elements being disposed in parallel rows upon said first surface, said parallel rows comprising a transmitting row of transmitting elements adapted to emit ultra wideband signals and a receiving row of receiving elements adapted to receive ultra wideband signals impingent thereon; said receiving elements being equal in number to said transmitting elements and disposed in said receiving row such that each of said receiving elements is aligned with respect to a corresponding transmitting element disposed in said transmitting row; each of said receiving elements being oriented upon said first surface with respect to said corresponding transmitting element so as to create a symmetric product response with respect to aspect angle.
