Abstract (en)
An antenna device (51a; 51b; 51c; 51d) designed to increase the volume that it occupies in a mobile communication apparatus as well as to achieve a large gain and a wide frequency band width without occupying a large area on a main circuit board (53a; 53b) and without changing the overall size of the mobile communication apparatus. The antenna device (51a; 51b; 51c; 51d) is also designed so that its impedance can be set or finely adjusted in a simple manner. The antenna device has a current supply element (52) and a radiating element (56a; 56b), and is mounted on a main circuit board (53a; 53b), with the current supply element (52) placed on a major surface of the main circuit board (53a; 53b), and with the radiating element (56a; 56b) accommodated in a gap formed between the main circuit board (53a; 53b) and an outer case (55). One major surface of the radiating element (56a; 56b) is opposed to the current supply element (52) and is maintained in contact with the same. <IMAGE>
