  • Electronic component for emitting and receiving radar signals
    Patent number: 11408974
    Abstract: The present disclosure relates to an electronic component for the bunched emitting and/or receiving of radar signals. For this, the electronic component comprises: a semiconductor chip, which is embodied to emit and/or to receive the radar signal by means of a primary radiator, and a support, on whose surface the semiconductor chip is arranged for electrical contacting. According to the present disclosure, the surface of the support has at least a first step embodied in such a manner that the radar signal in the case of the emitting and/or receiving is bunched approximately perpendicularly to the surface of the support. In this way, the electronic component-of the present disclosure is suited especially for those applications of radar based distance measurement, which benefit from bunched emitted and received radar signals.

  • Isolation structure of a large array antenna and an antenna
    Patent number: 11411308
    Abstract: The present disclosure discloses an isolation structure of a large array antenna and an antenna. According to an embodiment of the present disclosure, a boundary plate is disposed between array elements of a large array antenna. The boundary plate has hollowed-out areas and is perpendicular to a plane where the array elements are located. The hollowed-out areas of the boundary plate form sub-areas with staggered patterns in the boundary plate to allow a coupling path of signals of array elements generated at the boundary plate and a radiation path of the array elements to counteract with each other, so as to weaken the coupling between the array elements and improve the isolation between the array elements, especially the isolation between 3-5 db array elements.
