Abstract

The invention provides an antenna tuner and an antenna tuning system. The antenna tuner comprises a sampling circuit, an automatic tuning control circuit, an impedance transformer, a motor, a variable Inductor and an inductor. The sampling circuit is connected between an external transmitter and the impedance transformer in series, and is used for obtaining a phase comparison signal of the current and voltage values of the input signals, and outputting the phase comparison signal to the automatic tuning control circuit for measuring the phase difference; the automatic tuning control circuit is used for setting the impedance transformer and the inductor according to the working frequency, and setting the variable inductor through the motor according to the phase difference; the input signals are transmitted to the impedance transformer through the sampling circuit, and are further transmitted to the variable inductor through the impedance transformer, and the signals are coupled to an external antenna after being processed by the variable inductor. For the antenna tuner and the antenna tuning system, the phase difference is taken as the reference for adjustment, so that the tuning efficiency can be higher.

Description

technical field [0001] The invention relates to the field of antenna tuning, in particular to an antenna tuner and an antenna tuning system. Background technique [0002] Antenna auto-tuning technology is one of the key technologies. Most of the existing antenna tuners use a tuning method such as a separate impedance comparison. The parameters of the antenna are not tuned according to the phase difference value, so the tuning effect is not accurate enough, and when the antenna tuner does not store the tuning parameters, the antenna tuner needs to search for the required parameters, and the tuning time is lengthened. Contents of the invention [0003] The technical problem solved by the present invention is to provide an antenna tuner and an antenna tuning system, which can solve the problems of inaccurate tuning and long tuning time of the current antenna tuner. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the presen...
