By sequentially activating the pin diodes, the antenna main beam rotates by 90° in azimuth planes, with 30° deflection in the elevation plane. Moreover, the proposed antenna has a compact structure and good realised gain levels with a minimum value of 8 dBi. The measured results of the fabricated antenna prototype verify the simulation analysis.]]>519662664319<![CDATA[1 × 2 wideband patch-dipole antenna array with slot coupler]]>519664665662<![CDATA[Equivalent circuit model of MIMO based on coupling matrix]]>519665667289<![CDATA[Circularly polarised solar antenna for airborne communication nodes]]>519667669624<![CDATA[Non-resonant conductor reflectarray element for linear reflection phase]]>519669671401<![CDATA[Vertical and horizontal transmission enhancement between antennas using textile artificial magnetic conductor waveguide sheet]]>S_{21} has peaks of up to a maximum of −9.9 dB.

A second subject group (n = 10) completed the same activities to provide data for verification of the system. Results indicate that the classifier was able to correctly match each stride to its activity with >90% accuracy. Running and walking strides in particular matched with >99% accuracy. The outcomes demonstrate that a lightweight yet robust classification system is feasible for implementation on embedded hardware for real-time daily monitoring.]]>519675676226<![CDATA[Energy-efficient switching scheme in SAR ADC for biomedical electronics]]>519676678461<![CDATA[Using dispersive delay lines and time reversal for low contrast tumour detection]]>519678680328<![CDATA[Boost bulk-driven sense-amplifier flip-flop operating in ultra-wide voltage range]]>519680682560<![CDATA[Symbolic calculus for class of quantum computing circuits]]>Q gates is introduced, where Q represents the kth root of [0 1; 1 0], the unitary matrix of NOT, and k is a power of two. The controlling signals are GF(2) expressions possibly including Boolean expressions. The method does not require operating with complex-valued matrices. The method may be used to verify the functionality and to check for possible minimisation of a given quantum computing circuit using target lines. The method does not apply for a whole circuit if there are interactions among target lines. In this case the method applies for the independent subcircuits.]]>519682684201<![CDATA[Peak current-controlled CRM flyback PFC converter with square of line voltage-compensated primary current envelope]]>519684686264<![CDATA[Efficient scan matching method using direction distribution]]>519686688406<![CDATA[Theory of multi-level refractive geometry]]>a priori camera pose.]]>519688690363<![CDATA[Improved reversible data hiding for encrypted images using full embedding strategy]]>et al.’s method of reversible data hiding of encrypted images is proposed. The original work partitions the encrypted image into two sets, and only one set is used for data embedding. After carrying out a feasibility analysis, the full embedding strategy is employed. Accordingly, the data embedding capacity is dilated. In addition, the corresponding new fluctuation measurement is designed for the full embedding strategy. The experimental results reveal that the full embedding strategy is effective and also indicate that using the new fluctuation measurement the performance is further augmented. The proposed method outperforms other works in terms of performance.]]>519690691193<![CDATA[Robust estimation of target scale by removing outlier motion vectors using MAD]]>519691693389<![CDATA[Compressive wideband spectrum sensing based on single channel]]>519693695271<![CDATA[Network polar coded cooperation with joint SC decoding]]>519695697303<![CDATA[Reduction of space complexity based on symmetric TMVP]]>51969769977<![CDATA[Statistical characteristics of queue with fractional Brownian motion input]]>519699701146<![CDATA[Compact tri-band bandpass filter with stub-loaded stepped-impedance resonator]]>λ/4 stepped-impedance resonators (SIRs) with two separate coupling paths is investigated. A source–load coupling configuration is arranged to produce several extra transmission zeros for realising high-isolation performance. The centre frequencies of three passbands can be controlled by tuning the dimensions of two high impedance lines of the proposed open stub-loaded SIRs. The bandwidth of the three passbands could be conventionally controlled by adjusting the coupling strength of two coupling paths. The prototype of the BPF achieved insertion losses of 0.46, 1.05 and 1.4 dB at 0.82, 1.67 and 2.17 GHz, respectively. The measured results are in good agreement with electromagnetic simulation. The circuit only occupies 0.126λ_{g} × 0.108λ_{g}, where λ_{g} is the guided wavelength at a lower passband centre frequency.]]>519701703490<![CDATA[Wideband harmonic-tuned CMOS power amplifier with 19.5 dBm output power and 22.6% PAE over entire X-band]]>519703705409<![CDATA[Balanced dual-band BPF with intrinsic common-mode suppression on double-layer substrate]]>519705707510<![CDATA[Substrate-integrated waveguide phase shifter with rod-loaded artificial dielectric slab]]>519707709578<![CDATA[Textile-to-rigid microstrip transition using permanent magnets]]>519709710361<![CDATA[75 GBd InP-HBT MUX-DAC module for high-symbol-rate optical transmission]]>519710712627<![CDATA[Subwavelength grating Bragg grating filters in silicon-on-insulator]]>519712714270<![CDATA[Surface plasmon resonance sensor based on exposed-core microstructured optical fibres]]>x- and y-polarised peaks). Although the sensitivity of both the polarised peaks is very similar, the narrower linewidth of the y-polarised peak provides a much enhanced signal-to-noise ratio. The SPR sensing performance for a large refractive index (RI) range from 1.33 to 1.42 is evaluated. The sensor has higher sensitivity for detecting the high analyte RI. The feasibility of using EC-MOFs to develop a fast-response, real-time and distributed SPR sensor is determined.]]>519714715388<![CDATA[Analysis of low-frequency current ripple transmission in series-resonant LED drivers]]>519716717325<![CDATA[Vertical type double gate tunnelling FETs with thin tunnel barrier]]>I_{on} > 10^{−5} A/μm. Moreover, the on-current can be increased easily by adjusting the height of the source. However, since a hump phenomenon in the transfer curves occurred, the hump behaviour in the proposed device was investigated. After investigating it, the hump behaviour was found to have originated from two different tunnelling regions. Moreover, their threshold voltages show different values. Using a capping layer that can be made by gradual doping, the hump behaviour can be suppressed.]]>519718720445<![CDATA[Fast and convenient implementation of iterative eigenspace-based beamforming]]>519720722237<![CDATA[Energy-optimal base station density considering traffic dynamics]]>519722724120<![CDATA[Multiple-antenna phase-gradient detection for OAM radio communications]]>519724725343
