Abstract: A position detecting device serves for finding the distance between a specimen arranged in a conductive structure and a microwave antenna arrangement of the position detecting device, produced by an inventive method, on the basis of microwaves. The microwave antenna arrangement exhibits a dielectric antenna body provided at least in part with an electrically conductive coating, which constitutes a first and a second pole face on a coupling probe of the microwave antenna arrangement.

Abstract: The invention relates to an actuator, in particular pneumatic cylinder, with an actuator element movably located in a movement space of a housing and with a microwave position sensing device for detecting the position of the actuator element in the movement space, with a microwave aerial arrangement for the transmission of microwaves into the movement space forming a waveguide and for the reception of reflection microwaves generated by the reflection of the transmitted microwaves at the actuator element from the movement space, and with evaluation means for the generation of a position signal representing the current position of the actuator element from the reflection microwaves. In the actuator, it is provided that the actuator element has a groove arrangement with at least one groove for reflecting the microwaves.

Abstract: A position detecting device finds the position of a specimen arranged in a conductive structure on the basis of microwaves and includes an electrical circuit for the production and/or reception of the microwaves and a microwave antenna arrangement for emitting and/or receiving the microwaves. Said position detecting device includes a dielectric antenna body with a first pole face and a second pole face for the transmission of microwaves. The antenna body forms a component of the microwave antenna arrangement. The electrical circuit is at least in part arranged on the antenna body.
