Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a non-contact type data transmission body capable of changing a frequency band used for wireless communication without changing design of a main antenna.SOLUTION: A non-contact type data transmission body includes: an IC chip 10; a main antenna 20 with which the IC chip 10 is connected; and a sub antenna 30 for a booster that resonates with the main antenna 20 in a non-contact manner. The sub antenna 30 includes a first antenna 31 to which the main antenna 20 is adjacently arranged and a second antenna 32 whose end portions 32a and 32b are arranged to overlap with end portions 31a and 31b of the first antenna 31 in a planar view respectively so as to form a loop in a planar view without physically contacting with the first antenna 31.SELECTED DRAWING: Figure 1
【課題】主アンテナの設計を変更することなく無線通信に使用する周波数帯域を変更することが可能な非接触型データ受送信体を提供する。【解決手段】非接触型データ受送信体1は、ICチップ10と、ICチップ10が接続される主アンテナ20と、主アンテナ20と非接触で共振するブースター用の副アンテナ30とを備えており、副アンテナ30は、主アンテナ20が近接配置される第1アンテナ31と、第1アンテナ31と物理的に接触せず、平面視でループが形成されるように、端部32a,32bが第1アンテナ31の端部31a,31bと平面視でそれぞれ重なり合うように配置される第2アンテナ32とを備える。【選択図】図1 |
