Patent ID: 8870077

Claim:
A wireless integrated circuit device comprising: a wireless integrated circuit arranged to process a predetermined wireless signal; a loop-shaped electrode coupled to the wireless integrated circuit and including a coupling portion; and a first metallic electrode plate and a second metallic electrode plate coupled to the loop-shaped electrode, the second metallic electrode plate having an area larger than an area of the first metallic electrode plate; wherein the wireless integrated circuit and the loop-shaped electrode are sandwiched between the first metallic electrode plate and the second metallic electrode plate; the loop-shaped electrode is arranged such that a loop surface thereof is perpendicular to or tilted with respect to the first metallic electrode plate and the second metallic electrode plate; the loop-shaped electrode is directly electrically connected to the first metallic electrode plate via the coupling portion and is electromagnetically coupled to the second metallic electrode plate; and the first and second metallic electrode plates are used for transmission and reception of the wireless signal.
