Abstract: A system (20) and method (110) for controlling a radar antenna are provided. The method includes generating a first single beam antenna pattern, generating a second single beam antenna pattern and transmitting the first and second single beam antenna patterns. The method further includes using phase detection to determine angular information for a detected object based on a phase difference of received signals. The system includes a transmitter (22) configured to transmit pulses, a receiver (24) configured to receive reflected signals from the pulses, and an antenna (26) configured to generate a first antenna pattern and a second antenna pattern. The system further includes a processor (32) configured to determine angle information for a detected object based on phase detection of reflected signals from the first and second antenna patterns.

Abstract: A signal transmission apparatus (200) including a first waveguide (205), a second waveguide (207) and a third waveguide (215). The transitions between the first, second and third waveguides are substantially co-impedance matched. The signal transmission apparatus may be a multi-port device, and may be used to transition high frequency signals from one component to another in a variety of applications.
