“…In order to improve positioning accuracy, experts have also conducted relevant research. Ellahi et al [136] optimized the overall localization performance in the antenna array localization system, the effective bandwidth for base-band signal and the magnitude of the modulation frequency are reasonably allocated between the distance and direction information with a fixed effective bandwidth of the modulated signal. Chen et al [102] proposed a new indoor positioning framework by combining Bluetooth positioning technology with intelligent algorithms to improve accuracy.…”

With the development of urbanization, the problem of neurological diseases brought about by population aging has gradually become a social problem of worldwide concern. Aging leads to gradual degeneration of the central nervous system, shrinkage of brain tissue, and decline in physical function in many elderlies, making them susceptible to neurological diseases such as Alzheimer's disease (AD), stroke, Parkinson's and major depressive disorder (MDD). Due to the influence of these neurological diseases, the elderly have troubles such as memory loss, inability to move, falling, and getting lost, which seriously affect their quality of life. Tracking and positioning of elderly with neurological diseases and keeping track of their location in real-time are necessary and crucial in order to detect and treat dangerous and unexpected situations in time. Considering that the elderly with neurological diseases forget to wear a positioning device or have mobility problems due to carrying a positioning device, device-free positioning as a passive positioning technology that detects device-free individuals is more suitable than traditional active positioning for the home-based care of the elderly with neurological diseases. This paper provides an extensive and in-depth survey of device-free indoor positioning technology for home-based care and an in-depth analysis of the main features of current positioning systems, as well as the techniques, technologies and methods they employ, from the perspective of the needs of the elderly with neurological conditions. Moreover, evaluation criteria and possible solutions of positioning techniques for the home-based care of the elderly with neurological conditions are proposed. Finally, the opportunities and challenges for the development of indoor positioning technology in 6G mobile networks for home-based care of the elderly with neurological diseases are discussed. This review has provided comprehensive and effective tracking and positioning techniques, technologies and methods for the elderly, by which we can obtain the location information of the elderly in real-time and make home-based care more comfortable and safer for the elderly with neurological diseases.

In this paper, we have proposed a novel structure of Ka-band based phased array antenna with calibration function. In the design of Kaband antenna, the active phased array system is adopted and the antenna would work in the dual polarization separation mode. We have given out the schematic diagram for the proposed Ka-band antenna, where the Kaband antenna is in the form of waveguide slot array antenna, with 96 units in azimuth and 1 unit in distance. Each group of units is driven by a singlechannel Transmitter/Receiver (T/R) component, and the whole array contains 192 T/R components in total. The size of the T/R component is 55 mm (length) × 50 mm (width) × 5.8 mm (height), 3 Sub-micro Sub-Miniature Push-on (SSMP) blind sockets and a 21-core low-frequency socket are designed on the two sides of the T/R component. In order to meet the technical specifications of phased array antenna, the Ka-band transceiver component is designed based on Low Temperatrue Co-fired Ceramic (LTCC) technology to achieve miniaturization and lightweight. In our approach, the feed network includes two parts: transceiver network and calibration network. The transceiver network consists of 24 1:8 time-delay power dividers, 12 two-way power dividers and 2 six-way time-delay power dividers. The power supply required by the Kaband antenna unit is provided to each active component by the power module after Ka band wavelet control distribution. Simulation and measurement results are given in the form of standing wave and scanning capability.

Mehrpouyan has been a source of great inspiration for me. I joined BSU three weeks after the start date of the fall 2015 semester, but with the kind support of my supervisor, I was able to adjust well to the new environment. I am deeply impressed by the work ethic and professionalism of Dr. Hani. He will always be my mentor. Dr. Hani Mehrpouyan helped me understand advancements in millimeter-wave (mm-Wave) technology. Without the support of Dr. Hani, I would not have been able to accomplish my research goals. In Dr. Hani, I have found a person with the highest level of professionalism and a kind heart. Along with his research, Dr. Hani has also inspired me with his towering personality and gratitude. I am fortunate to be his student. I am also incredibly thankful to Dr. Nader Nafla and the ECE department at Boise State University for providing me with an extremely favorable environment for research and assisting me in my first patent. I am also thankful to Muhammad Kamran Latif, Ruhollah Amiri and Luka Dawood for helping and assisting me during my research. Muhammad Kamran Latif was always there to help. He also provided me with great emotional and logistic support during my time at Boise.
