    • PROBLEM TO BE SOLVED: To provide a position detection technique capable of minimizing the arranging intervals of antennas and measuring positions with high resolution in a system for communicating with IC tags and measuring their positions. SOLUTION: A position detection system is provided with an antenna module in which a plurality of antennas for receiving response radio waves, a response of IC tags when radio waves for detection are transmitted, and detects the positions of the IC tags on the basis of the state of reception of the response radio waves of each antenna. The plurality of antennas are aligned and arranged on induction interference preventing plates each having a V-shaped cross section at a tilt angle from a horizontal plane in which a magnetic substance is pasted to their surfaces. An induction interference preventing wall has a wedge-shaped cross section having a prescribed number of stepped sections, and a magnetic substance is pasted to their surfaces. The tips of the wedge shapes are fixed between the antennas of the induction interference preventing plates. A plurality of rows of the induction interference preventing walls are aligned and arranged to constitute the antenna module. COPYRIGHT: (C)2009,JPO&INPIT
    • 要解决的问题:提供一种位置检测技术,其能够在用于与IC标签通信并测量其位置的系统中最小化天线的排列间隔和高分辨率的测量位置。 解决方案:位置检测系统设置有天线模块,其中发送用于接收响应无线电波的多个天线,用于检测的无线电波的IC标签的响应,并且检测IC标签的位置 每个天线的响应无线电波的接收状态的基础。 多个天线对准并布置在感应防止板上,每个感应防止板具有与磁性物质粘附在其表面上的水平面成倾斜角的V形横截面。 感应防止壁具有具有规定数量的阶梯部的楔形截面,并且将磁性物质粘贴到其表面。 楔形的尖端固定在感应干扰防止板的天线之间。 感应干扰防止壁的多行排列并布置成构成天线模块。 版权所有(C)2009,JPO&INPIT
