In this paper, a multilayer patch antenna is proposed for implantable applications at the 401-406 MHz Medical Device Radiocommunications (MedRadio) and 433-434.8 MHz Industrial Scientific and Medical (ISM) bands. The antenna is composed of a spiral split extended into two layers to obtain miniaturization and coupled to an outer rectangular split ring to broaden the antenna bandwidth and increase its gain by 1 dBi. The proposed antenna has a relatively small size and good radiation characteristics for data transfer over 4 meters.

In this article, a low-cost switching hardware system is developed, and a Delay and Sum (DAS) algorithm is implemented for the early detection of breast cancer. It is based on the operation of a near field radar, with the use of ultra wide band (UWB) microwave signals through the emission and reception of electromagnetic waves from a set of switched antennas around the breast, that propagate through the breast tissue. It is composed of low cost, readily available commercial components resulting in a device that is both portable and with moderate cost. The operation consists on the frequency domain characterization of the medium permittivity, and the application of confocal microwave imaging techniques to estimate the location of regions with anomalous characteristics.

This work proposes an ultra-wideband Metamaterial (MM) absorber for smart electronic textile (e-textile) applications. The design is based on a novel cell geometry composed of two combined letter patches (A&S) printed on a grounded textile substrate. This unit cell geometry is specifically developed and optimized for millimeter-wave (mm-wave) applications. In this study, different types of textiles are considered, namely, Felt, Denim, and Polyester, and the achieved -10 dB reflective fractional bandwidths are about 50.36%, 44.49%, and 41.42%, respectively. A comparison between conventional counterparts PCB-based dielectrics (FR-4 and Rogers RT-5880) and textile-based fabrics (Felt, Denim, and Polyester) indicates that the bandwidths exhibited by textile fabrics are significantly wider. This study also demonstrates that the bending of textile-based materials has an inverse effect on the -10 dB bandwidth, as the material's surface curvature increases. The current design is more compact, thin, and more efficient in terms of absorptivity in comparison to other reported absorbers and structures in the literature. The obtained results can be considered promising for the development of ultra-wideband e-textile-based applications such as energy harvesting, health monitoring, and camouflage systems.

This paper presents a novel design and implementation of a highly directional wideband transmitarray (TA) antenna for 79 GHz radars. A novel method of using slot coupling between the receiving patch and transmitting patch is utilized for achieving wideband transmission phase. Compared to the traditional TA using slot coupling receive-transmit patch antenna unit cells, low profile of only four conducting layers are used. In addition, wide transmission bandwidth of 18.6% is achieved for the proposed unit cell. To realize a 3-bit phase delay, the distance between coupling slots and length of phase delay line are elaborately adjusted. Finally, to realize a highly directional radiation with the half-power beamwidth ≤3° in E-plane and H-planes, a TA antenna with circular aperture of 1976 unit cells was designed and measured. The measured results prove that its HPBW in E-plane is 2.8°, and in H-plane is 2.9°. In addition, it is observed a high aperture efficiency of 28% and a 2 dB gain bandwidth of 75-85 GHz can be achieved for the presented TA antenna. This TA antenna has been successfully implemented into commercial radar systems for obstacle detection and safe operation in applications of passenger vertical lift systems, such as elevators, lifts, etc., at China.

The development of wideband bandpass filter (BPF) is proposed based on substrate integrated waveguide (SI-W) technique which utilizes complimentary split ring resonator (CSRR) and defected ground structure (DGS). The proposed wideband SIW BPF that was designed and realized on an FR4 epoxy dielectric substrate implements CSRR structures on its SIW conductor surface and square DGS at the groundplane. Parametric study upon the characteristics of wideband SIW BPF without and with DGS is performed using simulation software to investigate the effect of its existence prior the hardware realization. The characterization results with the measured working bandwidth and fractional bandwidth of 8.36 GHz and 123.28%, respectively, show the good agreement each other with the simulated ones.

Noninvasive monitoring of blood pressure (BP) is crucial for diagnosis and management of hypertension. The current cuff-based, continuous BP measurement methods require uncomfortable arterial compression for every intermittent measurement. Thus, we suggest the development of a novel flexible, wearable and miniaturized microstrip antenna that can provide continuous and easy to use estimates of blood pressure. This wearable antenna is designed in High Frequency Simulation Software (HFSS) and dedicated for transmitting and receiving signals at 2.4 GHz. It is also compact of 35 x 35 mm2 with a epoxy substrate of dielectric constant 4.3. The patch presents a gain of 6 dB and resonance over the frequency band 2.3-2.6 GHz, which falls in the targeted industrial, scientific, and medical (ISM) band. In order to check the safety of using the antenna on human body, this paper presents a computer-based design of a human arm and applies the antenna on it. The specific absorption rate is 1.74 W/Kg, which is below the IEEE safety standard cut-off. The paper also presents a discussion on a newly proposed algorithm that relates the variation in electromagnetic waves along with variation in brachial artery specifications to estimate blood pressure parameters.
无创血压监测对高血压的诊断和治疗至关重要。目前基于袖带的连续血压测量方法需要在每次间歇测量时进行不舒服的动脉压迫。因此，我们建议开发一种新颖的柔性，可穿戴和小型化的微带天线，可以提供连续且易于使用的血压估计。这种可穿戴天线是在高频仿真软件(HFSS)中设计的，专门用于发送和接收2.4 GHz的信号。它也是紧凑的35 x 35 mm2与介电常数4.3的环氧基板。该贴片增益为6db，在2.3-2.6 GHz频段内谐振，该频段位于ISM(工业、科学和医疗)目标频段。为了检验天线在人体上使用的安全性，本文提出了一种基于计算机的人体手臂设计，并将天线应用于人体上。比吸收率为1.74 W/Kg，低于IEEE安全标准截止值。本文还讨论了一种新提出的算法，该算法将电磁波的变化与肱动脉规格的变化联系起来，以估计血压参数。

The proposed dual-band antenna is comprised of a 2x2 array operating at 26 GHz and 5.48 GHz (channel 96). The dual-band crossover consists of a microstrip-grounded CPW-microstrip interface transition. The measured design shows inter and intraband isolation better than 25dB with the crossover on the same plane with a maximum gain of 9.2dBi and 11.83 dBi for 26.25 GHz and 5.48 GHz respectively

In this work we propose a compact Multiple-Input Multiple-Output (MIMO) antenna for wrist-worn devices. The design is capable of unidirectional beamsteering across the entire horizontal plane, a property that is exploited for Angle of Arrival (AoA) Estimation based localization applications. The performance of the proposed system is evaluated using the high-resolution MUltiple SIgnal Classification (MUSIC) algorithm. Full -wave simulated results of the antenna in free-space show a peak realized gain of 5 dBi and estimated mean absolute errors < 0.36°. The gain and the estimated errors change to respectively 4.26 dBi and 0.45°, when using a human forearm phantom. The achieved results demonstrate the feasibility of the proposed antenna for localization applications using compact wrist-worn devices.

This study proposes a fast blind signal separation technique for human arterial pulse wave propagation measurement. One of the authors previously developed a blind signal separation method called physiological component analysis that uses mathematical modeling of the measured physiological signals, including the pulse wave propagation, and this method improves the signal separation accuracy when applied to array signal processing. Physiological component analysis, however, is known to require long computation times because it is based on high-dimensional global optimization. In this paper, we propose a method to reduce the dimensionality of the decision variables for the optimization process that uses the Schelkunoff polynomial method. Using this dimension reduction technique, we propose a new algorithm, called fast physiological component analysis, and the performance of this algorithm is evaluated using numerical simulations.
