摘要： PROBLEM TO BE SOLVED: To provide an antenna system, such that polarization characteristics of two orthogonal polarized waves of a folding antenna on a rectangular EBG structure are not caused to deteriorate.
SOLUTION: The rectangular EBG structure 1 has a periodic structure, comprising unit structures 5 repeatedly arranged in an X direction and a Y direction, and the unit structures 5, each having a structure which has a quadrangular shape when viewed from a Z direction and is not symmetric with respect to the diagonal thereof. Thus, the unit structures 5 are each made not symmetric about the diagonal thereof and then adjustments are made that in-phase frequencies in the X direction and the Y directions become equal to each other. The rectangular sheet structure 1, which is thus formed is used as a substrate of the antenna system, and then polarization characteristics of the folding antenna on the rectangular sheet structure are prevented from deteriorating.

摘要： PROBLEM TO BE SOLVED: To provide a low-loss EBG structure and an antenna device using it, and a wireless tag. SOLUTION: A loss of an EBG caused by a via 3 is reduced and a detrimental effect on antenna characteristics is suppressed by dispersing a path wherein a high frequency current flows by using a plurality of vias 3 connecting a top electrode 1 and a ground electrode 2 for each unit cell of the EBG structure and by reducing the loss generated when a high frequency current flows in the via 3 by enlarging a total surface area of the via 3. A surface area of a via can be enlarged by enlarging its outer shape while using a single via. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a high security function and prevent read/write for illicit purposes. SOLUTION: A function for detecting the intensity of radio waves from a reader/writer is provided in a tag so as to allow switching between a long distance mode and a short distance mode according to an instruction from the reader/writer. In the short distance mode, the tag responds only when the intensity of radio waves is higher than the specified, and does not respond when the intensity of radio waves is lower than the specified. In the long distance mode, response is not restricted. The long/short distance modes set according to the instruction from the reader/writer are stored in a nonvolatile memory in the tag, and thus a mode status is maintained, even out of a power supply area from the reader/writer, by reading the memory at next power supply.
