In order for it to be possible to manufacture a transition with a cost-effective stamping or diecasting or cold-molding process or with a plastic injection-molding process with subsequent metal plating, at least one ridge situated in the waveguide, which reduces the waveguide cross section in the direction of the stripline, has a cross section which tapers conically in the direction of the stripline.

Transition from a waveguide to a strip transmission line

According to the invention, a monostatic FMCW radar sensor for a vehicle for detecting objects is proposed in which at least one antenna feed in combination with a dielectric lens is embodied for both transmitting and receiving a corresponding echo signal. At least one antenna feed is connected to a ring mixer via a ratrace ring or double ratrace ring, so that an expensive circulator can be dispensed with. The high-frequency structure is advantageously embodied in planar microstrip form. A plurality of transmission and reception antennas are focused via one common lens.

Monostatic FMCW radar sensor

A radar transmitter/receiver arrangement for use, for example, in automotive vehicle control in which R.F. energy from a frequency modulated oscillator is applied to an antenna for transmission and to one input of a mixer by way of a rat-race device, and RF energy reflected from a target and received at the antenna is applied to another input of the mixer by way of the rat-race device.
