Radar sensor with a 180° Field of View

An apparatus working as an MmWave radar sensor module comprising:

• a mmWave integrated radar circuit entity having at least four receiving inputs, and at least two transmitting outputs;
• and
• an antenna structure having at least four radiation elements receiving mmWave signals, and at least two radiation elements transmitting mmWave signals, all the radiation elements being connected by mmWave electromagnetic transmission guides to the mmWave integrated radar circuit entity,
• wherein the middle points of radiation surfaces of said radiation elements build a symmetrical convex arrangement toward an observation area that is the main curve,
• wherein said radiation elements transmitting mmWave signals are arranged on the main curve in the middle of the main curve in symmetrical order such that the same number of radiation elements transmitting mmWave signals are arranged on each side of the main curve, in a case in which the number of radiation elements transmitting mmWave signals is even and one radiation element transmitting mmWave signals is arranged in the middle of the main curve and remaining radiation elements transmitting mmWave signals are symmetrically arranged on each side of the main curve, in a case in which the number of the radiation elements transmitting mmWave signals are odd,
• wherein said radiation elements receiving mmWave signals are arranged on the main curve on the left and right side of the radiation elements transmitting mmWave signals,
• wherein a first set of said radiation elements transmitting mmWave signals are arranged on the main curve in the middle of the main curve in symmetrical order such that
• one radiation element transmitting manWave signals of the same number is provided on each side of the main curve, in a case in which the number of portions of the radiation elements transmitting mmwave signals is even, and
• one radiation element transmitting mmWave signals is provided in the middle of the main curve and remaining radiation elements transmitting mmWave signals are provided symmetrically, in a case in which the number of portions of the radiation elements transmitting mmWave signals are odd,
• wherein said radiation elements receiving mmWave signals are arranged on the main curve on the left and right sides of the radiation elements transmitting mmWave signals,
• wherein a second set of said radiation elements transmitting mmWave signals are arranged on a secondary curve in the middle of the secondary curve in symmetrical order such that
• one radiation element transmitting mmWave signals of the same number is provided on each side the secondary curve, in case in which the second portions of the radiation elements transmitting mmWave signals is even, and
• one radiation element transmitting mmWave signals is provided in the middle of the main curve and remaining radiation elements transmitting mmWave signals are provided symmetrically, in a case in which the second portions of the radiation elements transmitting mmWave signals are odd,
• wherein said radiation elements receiving mmWave signals are arranged on the main curve on the left and right sides of the radiation elements transmitting mmWave signals, and
• wherein the secondary curve is displaced on the plane, which is parallel to a plane of the main curve.
