Abstract
A radar measuring device having a radio frequency unit for generating and/or receiving electromagnetic waves using an antenna for directional radiation of the electromagnetic waves, in which a waveguide for transmitting the electromagnetic waves is arranged between the radio frequency unit and the antenna is formed from two half-shells extending in the longitudinal direction of said waveguide.
Claims15
A radar measuring device having a radio frequency unit for generating and/or receiving electromagnetic waves using an antenna for directional radiation of the electromagnetic waves, comprising
- a waveguide for transmitting the electromagnetic waves at an operating frequency of at least 120 GHz between the radio frequency unit and the antenna, wherein
- a length of the waveguide in the longitudinal direction is greater than 30 times a smallest extension of the waveguide in cross-section, and
- the waveguide consists of two half-shells extending in the longitudinal direction of the waveguide.
