    Abstract: An antenna combination includes a feed-through having an input side including a connector for coupling to a transmission line connector and an output side including an inner cavity attaching to an aperture in a top surface or a nozzle of a tank. A foam filled dielectric rod antenna is coupled to the output side of the feed-through having a nose portion including a sub-portion within the inner cavity and a rod-shaped portion from beyond the inner cavity to an antenna launch end. The rod-shaped portion includes an outer solid dielectric material including a thickness transition region, wherein a thickness of the solid dielectric material decreases toward the antenna launch end to a constant minimum thickness shell region that extends to the antenna launch end. The outer solid dielectric material defines an inner hollow region. A dielectric foam fill material fills the inner hollow region.

    Abstract: A galvanic isolator includes a multi-layer printed circuit board (PCB) including a dielectric material having a top side and a bottom side. An RF transmission line is embedded within the PCB including a plurality of conductor traces spaced apart from one another to include a plurality of gaps (G1 and G2) in a path of the RF transmission line to provide an inline distributed capacitor that together with an impedance of the RF transmission line forms a bandpass (BP) filter. A top metal layer is on the top side and a bottom metal layer on the bottom side connected to one another by a plurality of metal filled vias on respective sides of the RF transmission line. The top metal layer and bottom metal layer each also include at least one gap.

    Abstract: Apparatus and associated methods relate to an in-hole current-measurement system having three or more magnetic-field sensors and a transient-disturbance selection module configured to form an output signal from a selected subset of sensor signals while decoupling the output signals from a non-selected subset of sensor signals during a predetermined time window when a disturbance signal is expected at the non-selected set of sensor signals. In an illustrative example, a disturbance producing operation may be performed on alternating subsets of sensors while the undisturbed subset of sensors measures an electrical current in the electrical conductor. For example, each selected subset of sensors may be aligned on an axis configured to be mounted perpendicular to current flow within a hole in the electrical conductor. Some embodiments may advantageously provide continuous electrical current measurement while being uninterrupted by the predetermined transient disturbances.

    Abstract: A dielectric hollow antenna apparatus includes a hollow inside tapered rod (e.g., a waveguide) with a flat section and a cap. The antenna further includes a feed through section, a feed pin, and a metal flange. A low loss dielectric material fills the hollow rod that protrudes beyond the metal waveguide to form a radiating element. The radiating element is designed in such a way to maximize radiation and minimize reflections over the antenna bandwidth. The feed through section reduces internal reflection and the waveguide is designed to include a rectangular waveguide that support a propagation (TE01) mode and the waveguide then transitions to a circular waveguide that supports another propagation (TE11) mode. The antennas can be employed for radar level gauging and withstand high temperature and possesses a small diameter that permits the antenna to fit in small tank nozzles.
