Title: ANTENNA ASSEMBLY HAVING ADAPTABLE PHASE RELATIONSHIP FOR ADJUSTING THE EMISSION CHARACTERISTIC
Abstract:
The invention relates to an antenna assembly (6) for a radar front end (60), comprising high-frequency antennas (4) for converting electromagnetic energy and a supply line network (1), by means of which the high-frequency antennas (4) can be connected to a transmitting unit and/or a receiving unit (61), the high-frequency antennas (4) and the supply line network (1) being formed by conducting tracks of a printed circuit board (68), and the supply line network (1) having a first supply line (2) in a first spatial direction (z) and at least two second supply lines (3) in a second spatial direction (y), the second supply lines (3) being connected to respective connection points (22) of the first supply line (2) and the high-frequency antennas (4) being connected to respective connection points (32) of the second supply lines (3). In order to make an emission characteristic of the radar front end (60) particularly easily adaptable to a particular intended use, according to the invention, the first supply line (2) and the second supply lines (3) are shaped as a loop (20, 30) between two adjacent connection points (22, 32) and a length (50, 52) of the supply line (2, 3) in question between the two adjacent connection points (22, 32) can be defined by means of the shape of the loop (20, 30) while the position of the high-frequency antennas (4) is held constant.
