摘要： A dielectric rod antenna assembly for a level measurement system. The antenna assembly includes a transition structure housed within a coupling sleeve. The transition structure includes a short-circuited waveguide filled with a dielectric material and an exciter element projecting through the waveguide into the material. The transition structure directs electromagnetic energy through the bottom of the dielectric material into a rod antenna attached to the bottom of the coupling sleeve for propagation within the container. The dielectric material includes a longitudinal axial bore having a tapered tip to provide a dielectric-lined waveguide. The bottom end of the dielectric is encircled with a metal ring of a diameter larger than the dielectric to smooth the transition into the rod antenna.

摘要： An antenna assembly suitable for use with a microwave-based level measurement system mounted on a vessel. The antenna assembly includes an installation thread, a shielded extension, and a rod antenna. The antenna assembly is screwed into a threaded portion in the opening of the vessel. The antenna assembly may be formed as a single integral unit molded from a polymer material. The antenna assembly may also be constructed with the installation thread, the shielded extension and the rod antenna comprising individual polymeric components which are welded together to form a unitary assembly. The polymer material is selected based on chemical resistant properties according to the application.
