Abstract
A wireless device having two appropriately placed antennas can reduce deterioration in properties of an antenna included in a casing. The wireless device includes upper and lower casings, a hinge part, and at least one transmission element. The upper casing houses a casing antenna resonating with a first frequency. The lower casing houses a matching circuit of the casing antenna and houses a radio unit circuit for processing a signal having a second frequency. The hinge part joins the upper casing with the lower casing, includes a built-in antenna resonating with the second frequency, and includes feeding sections for electrically coupling the matching circuit to the casing antenna. The transmission element is disposed on a signal path connecting the built-in antenna and the radio unit circuit, and (i) gives passage to the signal having the second frequency and (ii) blocks a signal having the first frequency.
