RFID tag and manufacturing method thereof
First Claim
1. An RFID tag having a tag antenna and an LSI chip, comprising:
- a power-supply pattern on which the LSI chip is mounted;
a patch antenna that functions as the tag antenna; and
an high-frequency connection section that makes a high-frequency connection between said power-supply pattern and said patch antenna.

Abstract
An RFID tag having a tag antenna and an LSI chip, comprising: a power-supply pattern on which the LSI chip is mounted; a patch antenna that functions as the tag antenna; and a high-frequency connection section that makes a high-frequency connection between the power-supply pattern and the patch antenna. The high-frequency connection section is formed, for example, by forming a slot in the patch antenna, layering one end of a small dipole antenna that functions as the power-supply pattern over the slot so that it crosses over the slot, and supplying power from the small dipole antenna to the patch antenna.

10. A manufacturing method for an RFID tag having a tag antenna and an LSI chip, comprising steps of:
-
forming a power-supply pattern on which an LSI chip is mounted, and a patch antenna that functions as a tag antenna on the surface of a double-sided print board by etching, so that the power-supply pattern and tag antenna are high-frequency connected;
making a conductive pattern on the rear surface of said print board ground; and
mounting said LSI chip on said power-supply pattern to create said RFID tag.
