Document Type and Number:
WIPO Patent Application WO/2020/043108
Kind Code:
A1
Abstract:
Embodiments of the present application provide an FM antenna circuit and a terminal device. The FM antenna circuit comprises a mainboard unit, a first matching circuit, a second matching circuit, a third matching circuit, and an FM processing unit, wherein a power supply end of the mainboard unit is connected to a power supply end of the FM processing unit by means of the first matching circuit; a ground end of the mainboard unit is connected to a ground end of the FM processing unit by means of the second matching circuit; the ground end of the mainboard unit is connected to an input end of the FM processing unit; an output end of the FM processing unit is connected to a signal end of the mainboard unit by means of the third matching circuit; the mainboard unit receives and sends an FM antenna signal to the FM processing unit; and the FM processing unit performs signal processing on the FM antenna signal, and sends the processed FM antenna signal to the mainboard unit, so that the mainboard unit outputs the processed FM antenna signal. The embodiments of the present application implement zero-clearance demands of an FM antenna while the receiving performance of the FM antenna meets real-time requirements.
