In this paper, a monopole UWB broadband antenna is designed, fabricated, and measured for wireless communication networks. The initial radiator model of the proposed has short-sleeve shape, to expand impedance bandwidth, right left angles are subtracted symmetrically from lower half radiator. matching improved by etching slots in feed line adding L-shaped patches on both sides line. results sho...
An ultra-wideband (UWB) self-complementary planar bow-tie antenna (SCPBTA) is proposed. The antenna consists of a printed conical horn-shaped (CHS) radiator and a counterpart CHS slot etched on a rectangular ground plane. The printed CHS radiator is connected directly to the 50Ω microstrip line by bending the end portion of the feed line. As a result, the antenna has a simple structure which do...
TORCH is a large-area time-of-flight (ToF) detector, proposed for the Upgrade-II of LHCb experiment. It will provide charged hadron identification over 2–20 GeV/c momentum range, given 9.5 m flight distance from LHC interaction point. To achieve this level performance, 15 ps timing resolution per track required. A prototype module having 1250×660×10 mm3 fused-silica radiator plate and equipped ...
Saat ini banyak kalangan yang memiliki kendaraan impian harganya terjangkau dengan kemampuan keuangan mereka. Namun masyarakat tidak mengetahui cara mengantisipasi dan mencegah secara dini kerusakan dari mobil diakibatkan berfungsinya sistem radiator pendingin mesin. Dibuat memonitor suhu air normal sesuai kerja disyaratkan pabrikan mengatasi overtemp mendadak dapat diatasi mobil. Sistem akan m...
CF4 is used as a Cherenkov gas radiator in one of the Ring Imaging Cherenkov detectors at the LHCb experiment at the CERN Large Hadron Collider. CF4 is well known to have a high scintillation photon yield in the near and far VUV, UV and in the visible wavelength range. A large flux of scintillation photons in our photon detection acceptance between 200 and 800 nm could compromise the particle i...
Modern wireless communications systems require improvement in capacity and data transmission speed. Adaptive array antennas separate spatially a desired wave from interference waves by controlling their radiation or beam pattern directivity. A digital beamforming (DBF) array performs adaptive beamforming by digital signal processing. However, the circuit scale, number of RF channels and power c...
