Abstract:
The present invention discloses a dual-polarized antenna that includes a ground plate, a feeding part, and a radiant plate. The feeding part includes a first feeding part and a second feeding part. The first feeding part includes a first dielectric plate, a first feeding layer, and a first transmission line. The second feeding part includes a second dielectric plate, a second feeding layer, and a second transmission line. The first dielectric plate and the second dielectric plate are placed perpendicularly to each other and are perpendicularly installed on the ground plate, and the first transmission line and the second transmission line are separated from each other.
Abstract:
A method and an apparatus for non-access stratum (NAS) message processing during handover in an evolved network are provided. The method includes the following steps. An evolved packet core (EPC) receives a message which indicates that a UE is being handed over sent by a source evolved NodeB (S-eNB), and stops sending an NAS message to the UE temporarily. The EPC receives a message which indicates that the UE returns to an S-eNB service area sent by the S-eNB. The EPC sends the NAS message to the UE through the S-eNB, if needed. With the method and the apparatus, the EPC can acquire a location of the UE in time in the case of a handover failure of the UE, a time limit of a retransmission timer is set precisely, and a specific implementation for forwarding an NAS message through an X2 interface is provided.
Abstract:
The present application provides a dielectric resonator, a dielectric filter, a base station and a method for fabricating the dielectric resonator or the dielectric filter. The dielectric resonator includes: a solid dielectric resonator body, a blind hole located on one side of the solid dielectric resonator body, a metalized layer covering both a surface of the solid dielectric resonator body and a surface of the blind hole, and a demetallized notch located at the metalized layer on the surface of the blind hole. The dielectric resonator provided in the present application can implement tuning of the dielectric resonator, and reduce impact on the resonance frequency of the dielectric resonator after the dielectric resonator is tuned, where the impact caused by that the demetallized notch is covered by a metal material in an assembly process of the dielectric resonator, and signal energy that is leaked from the notch is reduced.

This application provides a display panel and a terminal device. The display panel is provided with an effective display region, a hole-punch region located in the effective display region, and a border region surrounding the hole-punch region. The effective display region is provided with a plurality of first traces extending in a first direction, and second traces extending in a second direction, where the first direction is perpendicular to the second direction. In at least a portion of the first traces whose extension directions pass through the hole-punch region, portions of each first trace respectively arranged on two sides of the hole-punch region are connected by one of first windings, to ensure that the portions of the first trace respectively arranged on the two sides of the hole-punch region are connected, and at least a portion of the first windings are located in the effective display region.
