Abstract

The application provides an antenna detection device and electronic equipment. The antenna detection device includes a near field communication chip, a Hall chip, an antenna connection circuit, and an antenna bracket; the antenna bracket includes a mounting plate and a support portion, and the mounting plate and the support portion form an accommodating cavity , the near field communication chip and the Hall chip are arranged in the accommodating cavity, and the mounting plate is used to set the near field communication antenna; the Hall chip is connected with the first end of the near field communication chip, and the second end of the near field communication chip is connected with the antenna The first end of the connection circuit, the second end of the antenna connection circuit is used to connect the near field communication antenna; when it is detected that the antenna connection circuit is connected to the near field communication antenna, the Hall chip sends a start signal to the near field communication chip; The field communication chip starts the radio frequency sending and receiving functions under the condition of receiving the start signal. The present application can prevent the near field communication chip from being damaged due to excessive current.

Description

technical field [0001] The present application relates to the field of communication technologies, and more particularly, to an antenna detection apparatus and electronic equipment. Background technique [0002] NFC (Near Field Communication, near field communication) technology and functions are becoming more and more important in mobile phones. If the NFC antenna is not installed, when the NFC radio frequency transmission and reception functions are activated, the antenna path impedance will change from a dozen ohms to several ohms due to the absence of the NFC antenna, which will cause the NFC chip to be damaged due to excessive current. SUMMARY OF THE INVENTION [0003] Embodiments of the present application provide an antenna detection device and an electronic device to solve the problem of damage to an NFC chip caused by excessive current. [0004] In a first aspect, an embodiment of the present application provides an antenna detection device, including a near fiel...
