Special Issue Information

Dear Colleagues,

UWB radar is a new and powerful tool for non-invasive and non-intrusive measurements based on microwave electromagnetic fields and signal processing. Sensors with this technology are used for both short- and long-term monitoring and surveillance measurements exploiting remote sensing methodologies.

This Special Issue on UWB Systems in Biomedical Sensing invites unpublished papers exploring recent advances and developments in healthcare applications of UWB bioengineering measurement devices and related electronic implementation. This issue accepts both high-quality articles containing original research results and review articles and will allow readers to learn more about the potentials of UWB sensors in bioengineering devices.

Prospective authors are invited to submit unpublished work on the following research topics related to this Special Issue:

  • Wearable UWB sensors and devices;
  • UWB radar in medical physics;
  • Ultra-wideband biosensing and biosignal analysis and processing;
  • Microwave healthcare information systems and health informatics;
  • UWB system electronics for healthcare applications;
  • UWB cancer detection and imaging;
  • UWB sensors for detection of heart rate, respiratory movements, and human gate analysis;
  • UWB positioning radar for fall detection and activity monitoring of elderly and patients;
  • UWB in biomedical treatment;
  • UWB in wireless power transmission and harvesting;
  • UWB sensor materials, properties, concepts, fabrication, and testing techniques;
  • Application-oriented UWB printed sensor systems.

Quick on-scene assessment and early intervention is the key to reduce the mortality of stroke and trauma patients, and it is highly desirable to develop ambulance-based diagnostic and monitoring devices in order to provide additional support to the medical personnel. We developed a compact and low cost ultra wideband noise sensor for medical diagnostics and vital sign monitoring in pre-hospital settings. In this work, we demonstrated the functionality of the sensor for respiration and heartbeat monitoring. In the test, metronome was used to manipulate the breathing pattern and the heartbeat rate reference was obtained with a commercial electrocardiogram (ECG) device. With seventeen tests performed for respiration rate detection, sixteen of them were successfully detected. The results also show that it is possible to detect the heartbeat rate accurately with the developed sensor. Full article

The paper presents a highly efficient, low cost, ultra-wideband, microstrip monopole antenna for microwave imaging and wireless communications applications. A new structure (z-shape, ultra-wideband (UWB) monopole) is designed, which consists of stepped meander lines to achieve super-wide bandwidth and high efficiency. Three steps are used to design the proposed structure for the purpose to achieve high efficiency and wide bandwidth. The antenna bandwidth is enhanced by varying the length of meander line slots, optimization of the feeding line and with the miniaturization of the ground width. The simulated and measured frequency bands are 2.7–22.5 GHz and 2.8–22.7 GHz (156% fractional bandwidth), respectively. The dimensions of the antenna are 38 mm × 35 mm × 1.57 mm, and its corresponding electrical size is 2.41 λg × 2.22 λg × 0.09 λg, where guided wavelength λg is at the center frequency (12.75 GHz). This antenna achieved a high bandwidth ratio (8.33:1). The realized gain is varying from 1.6–6.4 dBi, while that of efficiency is 70% to 93% for the whole band. Radiation patterns are measured at four operating frequencies. It has an acceptable group delay, fidelity factor, and phase variation results that satisfy the limit of ultra-wideband in the form of the time domain. Full article
