| 摘要 |
The invention relates to a device for emitting high-frequency signals, comprising a signal generation unit, a signaling line, an emission cable and an antenna configured as a circular waveguide, said antenna being sealed in an end section by a rear wall. According to the invention, the signal generation unit creates the high-frequency signals, the signaling line conducts the high-frequency signals along the emission cable and said emission cable projects into the interior of the antenna and is positioned approximately parallel to the rear wall. The invention aims to provide a device for emitting electromagnetic waves, which is characterized by optimized emission characteristics. To achieve this, the distance (Z) between the emission cable and the rear wall of the antenna is approximately lambda/6, whereby lambda is the wavelength of the high-frequency signals borne by the antenna.
