摘要： A mesh processor divides a target device into a plurality of patches. A mutual impedance calculator computes a mutual impedance between the patches based on previously computed analytic solutions of a quadruple integration under the condition that the patches are rectangular in shape and are parallel or perpendicular to each other. Finally, an electromagnetic field intensity calculator calculates electromagnetic field intensity based on the computed mutual impedance.

摘要： The present invention relates to a tag-use antenna allowing a miniaturization while maintaining a constant minimal change of a communication distance. The tag-use antenna has a feed part of a folded dipole antenna of a size of 53 mm long and 7 mm wide being connected to, and equipped with, an LSI chip of Rc=500 ohms and Cc=1.4 pF and is covered with plastic resin 13 of the dielectric constant ∈r=3 and thickness of t=0.75 mm on both sides of the antenna. The dipole part of 1 mm wire path width of the tag-use antenna is formed in a rectangular spiral by being bent inward from both ends at bending parts at four places. The entire length of the dipole antenna when extending the four bending parts straight is featured so as to be shorter than one half of a resonance wavelength of the antenna. An inductance part is formed in the neighborhood of the center of the dipole antenna, and placed in the middle of the dipole antenna, which is formed in said rectangular spiral, of the dipole antenna.
