A wireless device includes a first antenna element (14) resonating with a first frequency, a first feeding point (14) coupled to the first antenna element and disposed on a ground plane (8) in the wireless device, a first matching circuit (16) of which first end is coupled to the first feeding point, a second antenna element (12) resonating a second frequency higher than the first frequency, a second feeding point (15) coupled to the second antenna element and disposed on the ground plane, a second matching circuit (17) of which one end is coupled to the second feeding point, and a radio circuit coupled via a transmission line (6) to a common connection point (18) shared by respective second ends of the first and second matching circuits. <IMAGE> |
