To solve the problem that a measurement up to a measured object using an electromagnetic wave transmission and reception requiring a design technique in which a frequency to be used is added is facilitated, and an effective use is promoted.SOLUTION: In a plurality of electromagnetic waves to be entered and reflected by a reception antenna in a measurement up to a measured object using an electromagnetic wave transmission and reception positioned at an almost same position of a transmission antenna and a reception antenna, an unnecessary reflection wave is reduced by providing a cylinder incidence hole in which an unevenness is applied to an inner wall of a material that reflects the electromagnetic wave to the electromagnetic wave incidence side of the reception antenna, and an effective use of the electromagnetic wave is easily promoted.SELECTED DRAWING: Figure 1 【課題】利用する周波数を加味した設計技術を要する電波送受信を利用した被測位物体までの測位を容易して電波有効利用を促進する課題があった。【解決手段】送信アンテナと受信アンテナとをほぼ同一位置に位置した電波送受信を利用した被測位物体までの測位における受信アンテナに入射される複数の反射した電波のうち不要な反射波を電波が反射する素材の内壁に凹凸を施した筒状の入射穴を受信アンテナの電波入射側に具備して低減させる構造とし容易に電波有効利用を促進する。【選択図】図１
