Abstract
A mobile communication device including an antenna element, a low-frequency blocking element, a first isolation circuit, a second isolation circuit and a high-frequency blocking element is provided. The antenna element converts a radio-frequency signal into an electromagnetic wave and generates a sensing signal in response to a proximity of an object. The antenna element includes a radiation portion and a parasitic portion which are spaced by a coupling gap. The low-frequency blocking element transmits the radio-frequency signal to the radiation portion. The first isolation circuit and a connection element are connected in series between the radiation portion and the parasitic portion, and the first isolation circuit blocks the radio-frequency signal. The second isolation circuit is electrically connected between the parasitic portion and a ground plane, and blocks the sensing signal. The high-frequency blocking element transmits the sensing signal from the antenna element to a sensing controller through a metal line.
