Claim Text:
1. A mobile communication device, comprising: an antenna element, converting a radio-frequency signal into an electromagnetic wave and generating a sensing signal in response to a proximity of an object, and the antenna element comprising a radiation portion and a parasitic portion which are spaced by a coupling gap; a low-frequency blocking element, electrically connected to the radiation portion, and the low-frequency blocking element receiving the radio-frequency signal and transmitting the radio-frequency signal to a feeding point of the radiation portion; a first isolation circuit, connected to a connection element in series between the radiation portion and the parasitic portion, and the first isolation circuit being configured to block the radio-frequency signal and transmit the sensing signal; a second isolation circuit, electrically connected between the parasitic portion and a ground plane, and the second isolation circuit being configured to block the sensing signal and transmit the radio-frequency signal; and a high-frequency blocking element, electrically connected between the parasitic portion and a metal line, and transmitting the sensing signal from the antenna element to a sensing controller through the metal line.
