摘要： Embodiments of this application disclose a communication apparatus. The communication apparatus includes a first filter, a second filter, and a coupling control unit. There is a first coupling rod in a 1 st resonant cavity of the first filter, and there is a second coupling rod in a 1 st resonant cavity of the second filter. The coupling control unit is located between the 1 st resonant cavity of the first filter and the 1 st resonant cavity of the second filter, and the coupling control unit is connected to the first coupling rod and the second coupling rod. The first filter and the second filter are configured to filter a radio frequency signal. The coupling control unit is configured to control connection or disconnection between the first coupling rod and the second coupling rod. If the first coupling rod is connected to the second coupling rod, an operating status of the communication apparatus is a power division state; or if the first coupling rod is disconnected from the second coupling rod, an operating status of the communication apparatus is a pass-through state. According to the communication apparatus in this application, a function of a reconfigurable cross coupler can be implemented by using a filter design, to reduce an insertion loss of a system.

摘要： This application provides a dielectric filter antenna, an electronic device, and an antenna array. The dielectric filter antenna includes a dielectric antenna and at least one layer of dielectric resonant cavity. The dielectric antenna is located at a top layer. The at least one layer of dielectric resonant cavity is located below the dielectric antenna. Energy coupling is performed between the dielectric antenna and a dielectric resonant cavity adjacent to the dielectric antenna. Materials of the dielectric antenna and the dielectric resonant cavity are a ceramic dielectric with a high dielectric constant. The energy coupling is performed between the dielectric antenna of the dielectric filter antenna in this application and the dielectric resonant cavity adjacent to the dielectric antenna, to avoid use of a transmission line or a matching circuit and avoid an insertion loss, thereby implementing a small size and good echo performance.

摘要： Embodiments of this application provide a dielectric filter and a communication device. The dielectric filter includes: a dielectric body, a first blind via and a second blind via that are provided in the dielectric body, a through hole located between the first blind via and the second blind via, and an insulating portion, where inner walls of the first blind via, the second blind via, and the through hole each are covered with a metal layer, and an outer surface of the dielectric body is covered with a metal layer; and the insulating portion is implemented by not covering a metal layer on a surface of the dielectric body, and the insulating portion partially surrounds the through hole. By using the dielectric filter in the embodiments of this application, when a signal wave entering the first blind via passes through the through hole, a phase of the signal wave negatively shifts for 90 degrees, and the signal wave is transmitted to the second blind via, so that an electric coupling of the dielectric filter is implemented. In such a manner of implementing the electric coupling, because a through hole is provided between the first blind via and the second blind via, modeling processing complexity is reduced. Moreover, such an electric coupling manner does not have a parasitic resonance effect and does not affect low band suppression.
