    • The invention relates to a measuring device, in particular a hand-held measuring device for locating objects enclosed in a medium, using high-frequency electromagnetic signals. Said device comprises a housing (82) and at least one high-frequency sensor, which is located in the housing and has a first antenna assembly (10) containing at least one first antenna element (12), the latter preferably emitting and/or receiving signals on a first polarization plane. According to the invention, the antenna assembly (10) has at least one additional antenna element (14), whose polarization plane is rotated in relation to the polarization plane of the first antenna element (12). The invention also relates to a method for locating objects enclosed in a medium, using high-frequency electromagnetic signals, in particular a method for operating a hand-held locating device comprising a plurality of antenna elements (12, 14; 11, 13), in which the measuring signal can be transmitted and/or received on different polarization planes.
    • 本发明涉及一种测量装置,特别是用于使用高频电磁信号定位包围在介质中的物体的手持式测量装置。 所述装置包括壳体(82)和至少一个高频传感器,所述至少一个高频传感器位于壳体中并且具有包含至少一个第一天线元件(12)的第一天线组件(10),后者优选地发射和/或 在第一偏振平面上接收信号。 根据本发明,天线组件(10)具有至少一个额外的天线元件(14),其极化面相对于第一天线元件(12)的偏振平面旋转。 本发明还涉及一种使用高频电磁信号定位在介质中的物体的方法,特别是一种用于操作包括多个天线元件(12,14; 11,13)的手持定位装置的方法, 其中测量信号可以在不同的偏振平面上传输和/或接收。
