    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： A radar antenna system comprises a first antenna, an additional first antenna, a second antenna, a guiding section, a branching section, an additional branching section, a filter section and an additional filter section. The branching section and the additional branching section are coupled in series in between the guiding section and the first antenna. The branching section couples the filter section to the guiding section and the additional branching section couples the additional filter section to the guiding section. The guiding section guides energy at a first, second and further frequency. The filter section couples the guiding section to the second antenna, blocks energy at the first frequency and passes energy at the second frequency. The additional filter section couples the guiding section to the second antenna or to a termination, blocks energy at the first frequency and passes energy at the further frequency.
