An antenna includes a first signal cable, a second signal cable, a combiner, a combined transmission line, a plurality of first filters and a plurality of cavities. The first signal cable is configured to transmit a first signal. Output ends of the first signal cable and the second signal cable are connected to an input end of the combined transmission line through the combiner. The plurality of first filters are each electrically connected to the first signal cable and are respectively located in at least two different cavities of the plurality of cavities. The plurality of first filters are configured to filter a second signal thereby generating the first signal.

Antenna and communication device

This application discloses a Bluetooth connection method, and relates to the field of short-range wireless communications technologies. The method includes: A terminal sends a service inquiry request to a Bluetooth device after the terminal and the Bluetooth device establish an asynchronous connectionless ACL link. The service inquiry request includes information about a service supported by the terminal. The Bluetooth device sends a service inquiry response to the terminal in response to the service inquiry request. The service inquiry response includes information about a service supported by the Bluetooth device. The terminal performs pairing with the Bluetooth device after the terminal receives the service inquiry response sent by the Bluetooth device. The terminal establishes a connection based on a first service to the Bluetooth device when both the terminal and the Bluetooth device support the first service. This reduces a period of time for establishing a Bluetooth service connection.

Bluetooth connection method and related apparatus

The present disclosure relates to phase shifters, antennas, and base stations. One example phase shifter includes a cavity, a built-in printed circuit board (PCB), and a stress relief portion. The stress relief portion is connected to the PCB, and the stress relief portion is configured to reduce a stress generated due to different coefficients of thermal expansion (CTE) of the cavity and the PCB.
