Abstract
PAGE 436 A novel subwavelength and low-profile element has been proposed by a group of Chinese researchers for reflected antenna array applications. A metallic hole is used to achieve smaller profile and period dimensions with the element obtaining a wide reflected phase shifting range. The results are validated with data gained from a fabricated prototype. PAGE 473 A classical expression of quantum microwaves after measurement, dependent on intrinsic correlated characteristics between measurement uncertainties and components of the microwave field, has been presented by researchers from China. The results are in agreement with experiments of entangled quantum microwaves and provide a more intuitive understanding of the wave behavior. Configuration of the proposed element. PAGE 434 A pair of researchers in China have designed and produced a slim dual-polarised antenna with omnidirectional patterns for WLAN applications. The slim structure has the advantages of light weight, convenient implementation, and easy fabrication due to the improved isolation between the two polarisations, with a rectangular loop acting as a tuner for the antenna impedance. Waveform schematics before and after measurement. PAGE 446 Improved energy harvesting efficiency in wireless sensors using a CMOS cross-couple RF rectifier has been presented by researchers in Korea. The proposed device uses a thick-oxide MOSFET to improve efficiency by reducing reversing leakage current and presents an 8% peak efficiency gain compared to conventional rectifiers. Feeding network of the proposed antenna. PAGE 438 Researchers from Taiwan have put forward a fully integrated bio-system with high sensitivity for electrochemical detection. The system measures the electrochemical characteristics using cyclic voltammetry whith the operating mechanism of the potentiostat behaving like a single-slope ADC. The system demonstrates feasibility in low-electrolyte environments. Voltage waveforms of internal nodes and output. Electrochemical detection system architecture.
