This paper presents a novel and efficient system for tracking of passive ultra high frequency (UHF) radio frequency identification (RFID) tags based on the phase difference of arrival technique. All required information for a tag position update is captured within only one communication cycle between a UHF RFID reader and a tag. The system provides two dimensional position updates that allow the tracking of a tag on arbitrary tracks. The current tag position is calculated analytically based on a specific bistatic reader antenna arrangement. Initial verification measurements in a realistic application environment show mean absolute errors of 8.4 cm and 1.3 cm for the x-coordinate and the y-coordinate, respectively.

The Load Modulated Balanced Amplifier (LMBA) uses a control signal (CSP), injected to the normally terminated port at the output coupler of a balanced amplifier (BA), to modulate the BA transistor's impedance. The hybrid circuit demonstrator described here uses metal-backed multilayer organic substrate and GaN discrete devices. Maximum output power levels above 39.5 dBm are achieved at around P3dB. DE above 60% is seen between 4.5 and 7.5 GHz for power back-off to 7 dB with a fixed CSP of 1 W, and the bias between 18 to 28 V.

This paper reports on an ultra-wideband (UWB) Schottky diode based balanced envelope detector for the L-, S-, C- and X- bands. The proposed circuit consists of a balun that splits the input signal into two 180° out of phase signals, a balanced detector, that demodulates the two signals, a low pass filter that rejects the second harmonic spurious from the Schottky diode and a bias tee that selects the optimum rectification point. The manufactured prototype is able to demodulate error free a 4 Gbps amplitude shift keying (ASK) signal at 4 GHz carrier frequency, leading to a record bitrate to frequency carrier ratio (Δb) of 100%. Besides this, the detector achieves error free demodulation for carrier frequencies between 4 and 8 GHz, while keeping the bitrate at 4 Gbps.

In this paper, we proposed a compact quad-band bandpass filter (BPF) using multilayer substrate technique. The filter is designed to have quad-band at 1.8, 2.4, 3.5 and 4.2 GHz. The four passbands are simultaneously generated by controlling the impedance and length ratios of the stub-loaded stepped impedance resonators (SIRs). By using the stub-loaded SIRs, the filter with closed passbands can be easily achieved. The frequency response of wide stopband is generated by using the defected ground structure (DGS) and having around −25 dB stopband from 4.2 to 12 GHz. The filter can provide the multi-path propagation to enhance the frequency response and achieving the compact circuit size. The measured results are in favorable agreement with the full-wave electromagnetic (EM) simulation results.

This paper presents an active UHF transponder designed for geological monitoring of boreholes drilled through ice sheets. It forms part of a phase-sensitive frequency modulated continuous wave (FMCW) radar system to measure the horizontal position of a borehole with depth. To distinguish the transponder response from stationary clutter, the transponder modulates the received signal before re-transmission to the surface radars. The transponder operates from 292 to 492 MHz with a gain around 18 dB. The transponder employs two novel antennas optimized for deployment within a 15 cm diameter borehole. The simulation and indoor laboratory measurement results of the transponder design are presented.

Building receivers (RXs) that operate above the transistor unity-power-gain frequency, fmax, is extremely challenging because an LNA-less architecture must be adopted. This paper reports on a 300-GHz CMOS RX operating above NMOS /max. Its conversion gain, noise figure, and 3-dB bandwidth are, respectively, −19.5 dB, 27 dB, and 26.5 GHz. The RX achieved a wireless data rate of 32 Gb/s with 16QAM. It shows the potential of moderate-/fmax CMOS technology to be used for ultrahigh-speed THz wireless communications.

This paper presents a novel wearable complementary split-ring resonator (CSRR) sensor for smart clothing to measure cardiorespiratory signs. The cardiorespiratory vital signs can be measured in the frequency and amplitude deviations of CSRR caused by the slight displacement from the chest. The heart signals can be extracted from the respiratory signals simultaneously by using a high sensitive CSRR sensor. Based on the proposed approach, the heartbeat can be significantly compared with traditional vital sign detection. Experiment results reveal that the CSRR can determine accurately the physiological signals. From the tracking resonant frequency and amplitude S21, the heartbeat rate and respiratory rate has errors of 0.01% and 0.04%, respectively. At a fixed frequency of 1.1 GHz, cardiorespiratory signals are measured to achieve low error of 0.01%. The proposed method is promising for healthcare applications.

The 300-GHz band enables ultrahigh-speed wireless communication because of its vast frequency range. We present a wireless link with a 300-GHz-band CMOS transmitter that improves the system signal-to-noise ratio (SNR) by using a frequency-doubler-based subharmonic mixer called a “square mixer” and an architecture with image and local oscillator (LO) suppression. It achieved wireless digital transmission at 56 Gbit/s over 5 cm with 16-QAM. In addition, we compare the performance of wireless links using a figure-of-merit (FoM). This wireless link has an approximately 7.5 times higher FoM than a recently reported wireless link based on a CMOS transmitter.

This paper presents a high sensitive microfluidics flowmeter based on a complementary split-ring resonator (CSRR) sensor which can detect a tiny amount of 1.65 μL unknown fluid using permittivity estimation. The CSRR can detect the spatial distribution of the fluid to calculate the tangent flow rate. A multiring with tapped feeding is designed to improve the sensitivity and wide measurable dynamic range and to enhance the high resolution of position. Analysis of the sensor was calculated to estimate the resonance frequency. Microfluidics was fabricated using a glass substrate to achieve a high quality factor sensor. From the measured results, there is an average error of 6% using a single ring Rogers sensor. Moreover, the average error can be reduced to 3.35 % using the glass sensor.
