A sealed utility transceiver assembly includes a transceiver board, a sealed housing, and a measure of liquid potting compound. The transceiver board includes multiple components and an antenna. The sealed housing includes a cavity within which to house the transceiver board. The measure of liquid potting compound encapsulates a portion of the transceiver board within the sealed housing, which portion does not include the entirety of the antenna.

A circularly polarized, multiband, and wideband antenna and can communicate with a GPS system. The antenna may include a driving element, first, second and third conductive parasitic elements electrically connected to the driving element, and a ground plane. The parasitic elements are provided with different lengths to provide for wider band operation with multiple resonant frequencies. The radiated wave has a low angle of propagation and travels for at least 1-2 miles.

Disclosed herein is a combination faceplate antenna holder for an electric utility meter.

A sensing device for a hydrant, the sensing device including a housing defining a portion of an operating stem of the hydrant; a sensor located entirely within the interior cavity of the hydrant body and configured to measure a property of a fluid of the fluid distribution system; and an antenna in communication with the sensor and positioned within the housing.

A field device having a metal housing, a connection line guided through a cable bushing and a radio module having an antenna, wherein the antenna extends, at least in sections, outside of the housing parallel to the connection line and in the cable bushing.

A passive radio repeater is built into a cover for a pit, in order to relay radio signals between a base station and a wireless communications device such as a water meter at the bottom of the pit. Within the external surface of the lid are provided upper and lower patch antennas. The lower antenna has a radiation pattern that extends downwards at right-angles to the plane of the lid, so that it communicates with the device at the bottom of the pit. The top antenna has a directional beam pattern in the elevation plane, achieved by exciting the top antenna in a mode that is higher than fundamental. The two antennas are coupled by a stripline printed circuit board provided with feeds to generate the required beam patterns.

A dual band antenna (AN) configured for being position on a surface of a pit lid and capable of wireless signal transmission at two frequency bands in response to an electrical signal applied via a feed wire. A convex conductive surface, e.g. 5 dome-shaped, is placed above a conductive ground plane element, wherein at least a part of an edge, e.g. 20-40% of the edge, of the dome-shaped radiator element is in electrical contact with the conductive ground plane element. Further, the convex conductive surface is connected via the feed wire. This antenna design allows first and second resonance frequencies within a factor of such as 1.8-2.2, 10 which allows the antenna to be designed e.g. for both of the frequency bands 450-470 MHz and 902-928 MHz which are relevant for meter reading data and with smaller dimension than what could be expected from conventional antennas. A housing with a convex top surface forms an enclosure around the antenna parts conductive ground plane element and the dome-shaped radiator element, the 15 housing has a bottom surface arranged to face the surface of the pit lid, and where the feed wire exits the housing.

An intelligent electronic device (IED) is provided. The IED includes a metering sub-assembly and an input base module sub-assembly. The metering sub-assembly is hinged to the input base module sub-assembly, where when in an open position, various cables, connectors, and input/output cards/modules are accessible. Various input/output cards/modules are interchangeable to add/change functionality and/or communication capabilities to the IED. In one embodiment, a communication card is provided with at least one antenna disposed internal or external to a housing of the IED.

A system for detecting the topology and phase information of an electrical power distribution system is provided. For example, the system includes a group of meters connected to an electrical power distribution system and can communicate with each other through local network connections such as a mesh network. Each of the meters is configured to generate and transmit voltage data to a correlator of the group of meters. The correlator calculates the correlations between each pair of meters in the group based on the voltage data received and further transmits the calculated correlations to a mapper through the mesh network. The mapper determines the topological or phase relationship between at least the group of meters based on the received correlations.
