Abstract
A radio-frequency signal grounding device for an antenna comprises: a substrate layer; a grounding transmission line on a first side of the substrate layer; a metal layer on a second side of the substrate layer, the metal layer including at least one gap such that the metal layer is divided into at least a first sub-region and a second sub-region, where the gap is configured to block at least one of a low frequency signal and a direct current signal; a metal plate; and a dielectric layer that is disposed between the metal plate and the metal layer. The radio-frequency signal grounding device can achieve good radio-frequency signal grounding and low frequency/direct current signal blocking within a limited space via a multi-coupling design.
