Title:
IMPEDANCE MATCHING CIRCUIT AND GNSS MODULE
Document Type and Number:
WIPO Patent Application WO/2023/098642
Kind Code:
A1
Abstract:
An impedance matching circuit and a GNSS module. The circuit comprises: a first end is connected to a collector electrode of a first triode by means of a first inductor and a first resistor, which are connected in series, and is connected to a base electrode of the first triode by means of a third resistor; an emitter electrode of the first triode is connected to a third end and is grounded by means of a second resistor and a second inductor, which are connected in series, and the base electrode thereof is grounded by means of a fourth resistor and is connected to a collector electrode of a second triode; a second end is connected to the collector electrode of the second triode by means of a third inductor and a fifth resistor, which are connected in series, and is connected to a base electrode of the second triode by means of a seventh resistor; an emitter electrode of the second triode is connected to a fourth end and is grounded by means of a sixth resistor and a fourth inductor, which are connected in series, and the base electrode thereof is grounded by means of an eighth resistor and is connected to the collector electrode of the first triode; and the collector electrode of the first triode is connected to the collector electrode of the second triode by means of a first capacitor. The present application can improve the performance of an antenna and increase the efficiency of the antenna on the basis of miniaturization of the antenna.
