A singing assisting system, a singing assisting method, and a non-transitory computer-readable medium including instructions for executing the method are provided. When the performed singing track does not appear in an ought-to-be-performed period, a singing-continuing procedure is executed. When the performed singing track is off pitch, a pitch adjustment procedure is executed.

The first end of the first radiation branch is coupled to a signal source. The second end of the first radiation branch is open. The second radiation branch has a first end and a second end. The first end of the second radiation branch is coupled to the signal source. The second end of the second radiation branch is coupled to the ground element. The length of the second radiation branch is substantially equal to that of the first radiation branch.

A mobile communication device includes an antenna element, a low-frequency blocking element, an isolation circuit, a first high-frequency blocking element and a second high-frequency blocking element. The antenna element converts a radio-frequency signal into an electromagnetic wave and includes a radiation portion and a parasitic portion. The parasitic portion and the radiation portion generate a first sensing signal and a second sensing signal in response to a proximity of an object. The low-frequency blocking element transmits the radio-frequency signal to the radiation portion. The isolation circuit is connected between the parasitic portion and a ground plane, and the isolation circuit blocks the first sensing signal and transmits the radio-frequency signal. The first high-frequency blocking element transmits the first sensing signal to a first sensing controller through a first metal line. The second high-frequency blocking element transmits the second sensing signal to a second sensing controller through a second metal line.
