Provided is a dual-band multimode antenna feed for a high-frequency band and a low-frequency band. The feed includes four high-frequency waveguide ports, where each high-frequency waveguide port is connected to a respective high-frequency input/output waveguide. Each high-frequency input/output waveguide includes a high-frequency waveguide aperture facing a first section for mixing electromagnetic modes in the E-plane. The first section is connected to a second section for mixing electromagnetic modes in the H-plane. The feed further includes a low-frequency waveguide port connected to a low-frequency input/output waveguide. A filter is arranged inside the first section to be transparent for plane wave modes exhibited at lower frequencies and reflecting for plane wave modes exhibited at higher frequencies.

According to an example embodiment, an electronic device may include a communication module including a first configuration pin, a processor configured to identify a device type of the communication module through the first configuration pin, and a first antenna device controlled by the communication module through the first configuration pin, in which the communication module is configured to transmit an identification signal for identifying the device type of the communication module through the first configuration pin for a time interval from the start of booting the processor to the completion of initializing the communication module, and transmit a first control signal for controlling the first antenna device through the first configuration pin after the time interval.

The present disclosure relates to a transmission mechanism for a base station antenna, and a base station antenna including the transmission mechanism. The transmission mechanism comprises: a worm gear unit, which is arranged on the first side of the reflector of the base station antenna and includes a worm driven by a motor and a worm gear meshed with the worm; a bevel gear pair unit, which is arranged on the second side of the reflection plate opposite to the first side and includes a first bevel gear and a second bevel gear meshed with each other, wherein the first bevel gear and the worm gear are coaxially installed on a first drive shaft; and at least one rack-and-pinion unit arranged on the second side of the reflection plate, wherein each rack-and-pinion unit includes a third gear and a rack element meshed with each other, all the third gears and the second bevel gears of the at least one rack-and-pinion unit are coaxially installed on a second drive shaft, and each rack element is fixed on the connecting rod of the phase shifter of the base station antenna for driving the connecting rod to move longitudinally. The transmission mechanism not only occupies a small total volume, but can also be installed in different spaces dispersedly, so that it can better adapt to the trend that the inner space of the base station antenna is getting smaller and more dispersed.
