| 摘要 |
<p>The invention relates to a position measuring device (30) comprising a microwave antenna arrangement (34) for determining the position (29) of an object to be measured (31) which can be moved in a space (12), on the basis of microwaves (32), said space at least partially forming a wave guide (33) for guiding the microwaves (32). The position measuring device is characterised in that the microwave antenna arrangement (34) comprises a dielectric antenna body (50) for injecting microwaves (32) into the wave guide (33) and/or extracting the same therefrom, a first pole face (51) and a second pole face (52) which are electrically insulated from each other by the antenna body (50) are coaxially arranged in relation to each other on the antenna body, forming a coaxial conductor section (57), and a front side (59) of the coaxial conductor section (57) comprising an annular insulation region (60) between the first pole face and the second pole face (51, 52) is oriented towards the object to be measured in the space (12) of movement.</p> |
