A High-Directivity Combined Self-Beam/Null-Steering Array for Secure Point-to-Point Communications

A high-directivity combined self-beam/null-steering array for secure point-to-point binary phase-shift keying communications is introduced. The system provides high directivity and reduced probability of interception using just two antenna elements. Using quadrature phase-shift keying modulators all...

More Information
Summary:A high-directivity combined self-beam/null-steering array for secure point-to-point binary phase-shift keying communications is introduced. The system provides high directivity and reduced probability of interception using just two antenna elements. Using quadrature phase-shift keying modulators allows for compact single-layer fabrication. The 2.4-GHz prototype is tested at interrogation angles of 0deg, -10deg, and +20deg, and demonstrates high signal-to-interference ratio directivity, completely disabling interception plusmn20deg from the direction of the interrogator. The system should find various applications where secure communications are required
