In this letter, an optically invisible antenna with high gain and wide band is investigated by utilizing transparent ionic liquids for millimeter (mm)-waves vehicular communications. The consists of liquids, acrylic containers, a conductive film (TCF). wideband high-gain operating characteristics are achieved using the low-loss frequencies-insensitive liquids. Meanwhile, introducing surface-mounted horn structures TCF walls, antenna's radiation has been improved. Measured results agree well...
A novel optically transparent (OT) 3D printed liquid antenna is proposed for mm-waves vehicular networks. The comprised of a resin container, ionic liquids, and conductive film (TCF). high-order mode excitation the can expand its bandwidth enhance directivity. Meanwhile, cone-shaped director introduced, which not only improves impedance matching performance but also enhances radiation gain. TCF be equivalent to metallic ground, increase transparency while maintaining high measured results...

ABB's isolated parallel ring bus (IPRB) architecture with static uninterruptible power supplies (UPS) provides a solution excellent scalability, sharing, and fault handling capability. Critical components in data center distribution system are modeled for simulations. In the modeling approach, balance is struck between computation speed fidelity such that useful simulation results can be obtained use planning, design, protection. The UPS model includes low short circuit current modes....
The imaging quality of THz-SAR is sensitive to the parameters. small estimated parameter deviation vehicle velocity, radar squint angle and target distance deteriorate result. In this paper, method range Doppler algorithm (RDA). velocity are searched based on Entropy Minimization Criterion (EMC) at first. Then improved azimuth match-filter function constructed by rate, which obtained from time-frequency distribution echo. Finally, a more focused image after match filtering with function....
QTT is a steerable 110 m radio aperture telescope that will be built in Xinjiang province of china, with frequency range from 150 MHz to 115 GHz. Site RFI levels clearly an important issue for such sensitive instrument. Therefore, we have developed automated highly and reliable spectrum monitor system detected signal characteristic analyzed, quasi-real-time measured method was employed long-term monitoring, used the HDF5 data format storage management. This working well at site long time,...
The proposed Qi Tai 110m radio Telescope (QTT) is a fully steerable single-dish telescope with an observing frequency coverage from 150 MHz to 115 GHz. QTT will play important role for fundamental research fields of astronomy, such as pulsars, molecular spectral lines, active galactic nuclei, and VLBI observations [1]. In order mitigate the potential interference in buildings at site, low-cost shielding scheme buildings, medium low level RFIs. measured effectiveness shows that achieves our...
In this letter, a concept of inflatable wideband stacked microstrip antenna with circular polarization is proposed.
