Abstract

An electronic device includes a helical resilient member serving as an electrical inductance element. The electronic device also includes an antenna, a signal feeding line, and a transmitting/receiving module. The helical resilient member has first and second ends with a predetermined number of turns of coil arranged therebetween the first and second ends, and is made of electrically conductive materials so that the turns of coil defines an electrical inductance. The signal feeding line is connected between the helical resilient member and a signal feed point of the antenna. The transmitting/receiving module is connected to the helical resilient member so as to couple the inductance of the helical resilient member to the transmitting/receiving module.
