| 摘要 |
<p>The invention relates to a method and a position measuring device (30) comprising a microwave antenna arrangement (34) for determining a position (29) of an object to be measured (31) which can be moved in a space (12), on the basis of microwaves (32) of at least one first frequency (f1), said space at least partially forming a wave guide (33) for guiding the microwaves (32). The microwave antenna arrangement (34) comprises a dielectric antenna body (50) on which a first pole face (51) and a second pole face (52) which are electrically insulated from each other by the antenna body (50) are arranged, for injecting microwaves (32) into the wave guide (33) and/or extracting the same therefrom. The position measuring device (30) comprises a high-frequency microwave emission/reception device (35) for transmitting and receiving microwaves (32) in the at least first frequency (f1) for determining the position of the mobile object to be measured (31), and in at least one second frequency (f2) for determining at least one electrical property of the antenna body (50). The position measuring device also comprises measuring means (40) for determining the at least one electrical property of the antenna body (50) on the basis of microwaves (132) reflected inside the antenna body (50), in the at least one second frequency (f2).</p> |
