Abstract
An antenna includes a substrate, a first array of transmit antenna patches on the substrate, and a second array of receive antenna patches on the substrate. A spatial orientation of the first array with respect to the second array is selected based on a predetermined desired radiation coupling between the first array and the second array. The antenna can be part of an automotive radar sensor.
Claims15
An antenna, comprising:
- a substrate having a planar surface defining a plane;
- a first planar array of transmit antenna patches on the planar surface of the substrate in the plane, the transmit antenna patches being disposed along a longitudinal axis of the first planar array;
- and
- a second planar array of receive antenna patches on the planar surface of the substrate in the plane, the receive antenna patches being disposed along a longitudinal axis of the second planar array;
- wherein
- a spatial orientation of the first planar array with respect to the second planar array is such that the longitudinal axis of the first planar array and the longitudinal axis of the second planar array are substantially nonparallel and define a tilt angle defining an angular orientation between them within the plane, the angular orientation being selected based on a desired radiation coupling between the first array and the second array.
