A novel class of balanced-to-single-ended (BTSE) out-of-phase/3-dB power divider with added high-selectivity filtering and RF-input-quasi-absorptive capabilities is reported. This type RF multifunctional power-division/filtering component consists a planar/single-layer mixed-mode magic-T on microstrip-to-slotline transition resistively-terminated multistage transmission-line section loaded at its <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML"...
The theoretical design and practical development of RF analog filtering devices with co-integrated lowpass, single <inline-formula xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"> <tex-math notation="LaTeX">$\bm{/}$</tex-math> </inline-formula> multi-band bandpass, highpass transfer functions is reported. For this purpose, two different classes generalized frequency transformation that convert the equivalent normalized lowpass filter prototype into...
A class of reflectionless RF bandpass filters (BPFs) with wideband quasi-constant in-band group-delay response in transmission for high-data-rate digital-communication systems is presented. These BPFs are developed by exploiting multilayer microstrip-to-microstrip vertical transitions and lossy multi-section microstrip lines complementary-diplexer-based architectures. two-port-reflectionless BPF low-in-band-variation equi-ripple-type characteristics firstly realized using two...
In this paper, an overview of novel design and integration approaches for improved performance UHF radio frequency identification (RFID) tags with embedded power source sensing capability is presented. Ultra-low-cost organic substrates, such as inkjet-printing are investigated the band. The proposed technology could potentially revolutionize sensor nodes RFID various ubiquitous "cognitive intelligence'" applications security, logistics, automotive pharmaceutical.

Water in Lower Aquifer of Quaternary is one the mine water inrush sources during working faces being mining Northern Section 8 Coal Seam West No.1 Mining Area. flowing fractured zone, F1 fault, F22-a fault and F48 are main water-conducting channels mining. According to analysis geology hydrographical area, combined with “Water Prevention Regulation Mines” “Regulations pillar leaving coal under building, water, railway mail shaft tunnel”, stope layout was optimized, i.e. minimum waterproof...
The coupling-routing-diagram (CRD) modeling of a class quasi-elliptic-type diplexer with predistorted flatenned passbands is reported. By retuning several admittance inverters the after considering finite quality factor (Q) its resonating nodes, in-band insertion-loss variation produced in channelizing filters can be compensated. As such, an effective Q terms for being much higher than that intrinsic to employed microwave technology achieved. For illustration purposes, CRD two examples...
