Abstract
Low-profile radar reflectors are provided for reradiating when illuminated by a vertically-polarized incident wave generated by an automotive radar. One example reflector includes a ground plane, a substrate having a top surface and a bottom surface, and radiating elements positioned on the substrate. Each radiating element includes opposing vertical metallic side segments connected to the ground plane, and a horizontal metallic segment extending between the opposing vertical metallic side segments and along the top surface of the substrate. The horizontal metallic segment of each radiating element has a defined length such that, when the radiating element is illuminated by a vertically-polarized incident wave from an automotive radar, each radiating element is at its resonance causing currents in the opposing vertical metallic side segments to flow in the same direction and reradiates back to the automotive radar. Other example low-profile reflectors and methods of fabricating low-profile reflectors are also disclosed.
