Before describing the antenna detection system in detail, the working principle and the antenna detection method of the antenna are briefly summarized to further clarify the technical problem that the antenna detection system provided by the present application can solve.
An antenna is an indispensable important component of any electronic device requiring wireless communication, and functions to radiate and receive a radio frequency signal, which is an electromagnetic wave modulated to have a certain transmission frequency.
Specifically, when the antenna performs signal transmission, the transmitting end device sends the generated high-frequency oscillation current to the antenna, and the antenna converts the high-frequency oscillation current into control high-frequency electromagnetic waves (i.e., radio frequency signals) and radiates the control high-frequency electromagnetic waves to the surrounding space in the form of waves. When the antenna receives signals, the antenna converts the intercepted high-frequency electromagnetic waves into high-frequency oscillation current, and then the high-frequency oscillation current is sent to receiving end equipment.
In the production and assembly process of the electronic device, the antenna needs to be installed in the electronic device (for example, an interactive flat panel), but since the antenna is not an integrated antenna and may be composed of several components, there may be a case where the assembly is incorrect, and the wireless signal transceiving function of the electronic device may be affected.
At present, the detection mode of the antenna is to judge whether the antenna can normally work on the electronic equipment by detecting the receiving and sending conditions of the radio frequency signal after the antenna is installed on the electronic equipment, so as to realize the wireless communication function of the electronic equipment, but the detection accuracy of the receiving and sending of the radio frequency signal can be ensured without being interfered by external signals, so that the technical problem of antenna detection cannot be solved by a mode of detecting the whole electronic equipment through a router at the end of an assembly line of the electronic equipment, and the mode of directly moving the whole electronic equipment into a darkroom is not suitable for the production line detection of large-scale electronic equipment such as an interactive flat plate and the like.
