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.
