Abstract

Embodiments of the present application provide an antenna system and a control signal transmission method, which relate to the communication field, and realize transmission of control signals without adding additional components when the CPU and the antenna are not deployed on the same printed circuit board PCB. The antenna system may include: a first PCB and at least one antenna, and the at least one antenna is respectively deployed on PCBs other than the first PCB. The first PCB is respectively connected to each antenna in the at least one antenna through cables. The first PCB is used to send an AC input signal and a DC control signal to each antenna through cables. Wherein, the DC control signal may include any one of the following signals: a first level for turning on the diode with the cathode grounded, a second level for turning off the diode, and a third level for turning on the diode with the anode grounded.

Description

technical field [0001] The present application relates to the communication field, and in particular to an antenna system and a control signal transmission method. Background technique [0002] With the rapid development of communication technology, wireless-fidelity (Wi-Fi), a wireless local area network standard based on the Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE) 802.11 standard, is widely used in homes, offices and other Indoor / outdoor environment. In each application scenario, the horizontal coverage and wall penetration performance of ceiling-mounted Wi-Fi devices (access points) are important indicators of Wi-Fi devices. Therefore, antennas with high directional gain and adaptively switching beams are extremely important for Wi-Fi devices. [0003] The beam switching of the antenna is controlled by a central processing unit (CPU), and the CPU obtains different beams of the antenna by sending differe...
