Duplicates of crystal structures are flooding databases, implicating repositories hosting organic, inorganic, and computer-generated crystals. While some database administrators are mum about ...
Abstract: A bidirectional multibeam transmit-reflect-array (TRA) antenna has been proposed for the space–air–ground–sea integrated network (SAGSIN). The TRA consists of alternating transmission ...
40 GHz Beam-Steering Two-Elements Array Antenna Using GaN Varactors for Millimeter-Wave Applications
Abstract: A continuously steerable beam patch antenna array employing a classical phase shifter based on GaN HEMTs is presented. Here the GaN HEMTs are used as varactor diodes to achieve the ...
