Abstract

The present application provides an external antenna circuit, the circuit includes: a thermistor connected to the first end of the first capacitor C1, the second end of the first capacitor C1 connected to the first end of the second capacitor C2, the The second end of the second capacitor C2 is connected to the terminal peripheral interface, wherein the second end of the first capacitor C1 is connected to the first end of the thermistor, the first end of the discharge tube, and the first end of the inductor L One end of the voltage regulator source is connected to one end of the preset resistor R1, the other end of the preset resistor R1 is connected to the first end of the inductance L, and the second end of the inductance L is connected to the first capacitor C1, the The common end of the thermistor and the discharge tube, the second end of the thermistor is grounded, and the second end of the discharge tube is grounded; the voltage acquisition device is connected to the preset resistor R1 and the inductor L public end. The above solution can provide the antenna with the functions of temperature detection and lightning protection on the premise of realizing the communication function of the antenna.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to an external antenna circuit and an external antenna device. Background technique [0002] An antenna (antenna) is a transformer that converts a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. With the rapid development of communication technology, various wireless communication devices appear one after another, and the antenna is used as a guarantee for the normal communication of various communication devices. The antenna function and appearance size will affect the use effect of wireless communication devices and the user experience. [0003] At present, many communication devices use external antennas, and there are more and more types of external antennas, such as magnet-adsorbed suction cup antennas, rod-shaped glue rod antennas or adhesive-backed patch antennas, et...
