Patent ID: 8779982

Claim:
A portable wireless device comprising: a body; a first antenna unit that communicates with an external device by way of a first frequency band, wherein the first antenna unit comprises a spiral antenna pattern comprising a line configured in a spiral shape; a second antenna unit that is disposed in the vicinity of the first antenna unit and communicates by way of a second frequency band that overlaps a high-order secondary resonance point of the first frequency band; and a reducing unit for reducing a frequency component in the high-order secondary resonance point of the first frequency band, wherein the reducing unit comprises a band-limiting element provided in the middle of the line, wherein the band-limiting element comprises a parallel resonance circuit, wherein the band-limiting element has high impedance in the second frequency band and low impedance in the first frequency band, and wherein the band-limiting element is provided on a side of the spiral antenna pattern that is closest to the second antenna.
