摘要

The invention relates to the field of fixed wireless telephones, and it discloses a method for using a handle rope of a fixed wireless telephone as an FM antenna and the fixed wireless telephone. An FM antenna signal access point is disposed on one of the four conducting wires connecting a baseband chip and a handle; a first magnetic bead is connected between said FM antenna signal access point and the output end of said baseband chip in series; and an FM frequency selection circuit is lapped on the FM antenna signal access point, wherein said FM frequency selection circuit is connected with said FM frequency modulation chip. The method for using a handle rope of a fixed wireless telephone as an FM antenna and the fixed wireless telephone provided by the invention can not only save the cost, remain the appearance of the fixed wireless telephone, but also enable the antenna to achieve a good receiving performance, because the handle rope of the fixed wireless telephone is used as the FM antenna and the corresponding frequency selection circuit is added.
