摘要： An active passive antenna arrangement as made up of an array of 5G antennas interleaved with multiband antenna structures that may be low band (LB) passive antennas. The 5G antenna array may be a mMIMO active array. The LB antennas are formed using conductive elements on thin supporting sheets that fit within the space between the 5G antennas. The substrates, and hence the radiating elements of the LB antennas, may be arranged so as to generally appear to form four sides of a rectangular box with the top and bottom surfaces removed. Thus, the LB antennas may be thought of as having been “slipped in” amongst a preexisting array of 5G antennas. Each LB antenna may surround one or more of the 5G antennas and 5G antennas of the array may also be external to an LB antenna.

摘要： A pressurization dehydrator comprising an air compressor and a controller connected to enable automatic operation of the dehydrator. The dehydrator is implemented as a freestanding, bench-top unit having a housing that encloses a baffle plate on which the compressor is mounted. The bottom panel of the housing is affixed to the plate using dumpers inserted therebetween. The plate has legs protruding through the corresponding openings in the bottom panel for supporting the whole unit in the upright position on the bench top. Some or all of the legs may not have contact with edges of the openings. In operation, the legs provide an efficient mechanical pathway for transferring some vibrational energy of the plate to the bench top, thereby diverting said energy away from the housing. The circuit board of the controller is affixed to the housing, which beneficially reduces vibration levels transferred to the electronic components of the controller.

摘要： An antenna assembly and method are disclosed. The antenna assembly comprises: a printed circuit board assembly having a radiating element layer and a choke structure, the choke structure having a central conductor and a shielding structure, wherein the central conductor comprises at least a portion of the radiating element layer. By providing a printed circuit board assembly having a radiating element layer and a choke structure which utilises a portion of the radiating element layer, the manufacture of the radiating elements is simplified.

The support member includes a first portion of a conductive arm of a dipole antenna, and a first portion of a conductive arm of another dipole antenna. A second portion of the conductive arm of the dipole antenna extends from the first portion of the conductive arm of the dipole antenna towards the first portion of the conductive arm of the other dipole antenna, defining a gap in a direct current path between the second portion of the conductive arm of the dipole antenna and the first portion of the conductive arm of the other dipole antenna.

摘要： The present disclosure aims to provide a method and device for virtual port mapping of massive MIMO. The present disclosure maps one or more transceiver units to a virtual port by performing hybrid beamforming for at least one transceiver unit in massive MIMO, and then performs digital precoding based on the virtual port. Compared with the prior art, the present disclosure is an adaptive technology adapted to the existing architecture; the present disclosure is based on virtual port mapping technology, which reduces the number of ports required for baseband processing, thus simplifying baseband processing, and furthermore, the present disclosure does not reduce the number of antenna elements utilized; the present disclosure can utilize digital precoding in hybrid beamforming to perform energy efficiency management; the present disclosure can be used more flexibly as a medium-term beamforming scheme in different frequency domain and time domain, while traditional analog beamforming is a long-term/semi-static beamforming scheme in time domain.
