Summary:To provide a wearable battery-less sensor with a sensor terminal including a two-layered microstrip antenna with a given thickness and enough flexibility as a whole at a low cost.SOLUTION: The microstrip antenna includes: a first metal layer constituting an antenna element; a second metal layer constituting the ground; and a flexible material separating the first metal layer and the second metal layer by a predetermined distance. The first metal layer and the second metal layer are formed of a metal having flexibility or a metal foil formed over a material having flexibility. The first metal layer and/or the second metal layer are not adhered to the flexible material, but are held in contact with each other by a pressing means.SELECTED DRAWING: Figure 1 【課題】所定の厚さを有した2層構造のマイクロストリップアンテナを備えたセンサ端末に、全体として充分な可撓性を持たせて、ウェアラブルな電池レスセンサを安価に提供する。【解決手段】マイクロストリップアンテナが、アンテナ素子を構成する第1金属層と、グランドを構成する第2金属層と、前記第1金属層と前記第2金属層とを所定の距離だけ離隔させるフレキシブル材と、を備え、前記第1金属層及び前記第2金属層は、フレキシブル性を有した金属によって形成されるか、または、フレキシブル性を有する材料上に形成された金属箔で形成されており、前記第1金属層、及び/又は前記第2金属層が、前記フレキシブル材と接着されずに、密着手段によって密着している。【選択図】図1
