1B2: Workshop 2: Passive human detection, localization, and posture identification, using radio technologies
Chair: Takuya Sakamoto (Kyoto University, Japan)
Speakers: Assistant Prof. Dr. Yang Miao (Twente University, the Netherlands), Prof. Dr. Minseok Kim (Niigata University, Japan), Prof. Dr. Jörg Schäfer (Frankfurt University of Applied Sciences, Germany), Prof. Dr. Stefano Savazzi (Consiglio Nazionale delle Ricerche (CNR), Italy)
Abstract
This workshop is to address one of the most challenging issues in wireless radio based assisted living, i.e., to dynamically detect, localize and track, and identify the postures of multiple humans in indoor environment.
As Japanese, Europeans, etc., are growing older and healthier, these societies face tremendous challenges in securing the future wellness of a larger segment of its population requiring special attentions, e.g., the elderly and the physically impaired. This is expected to have a great impact on the future advancement of these societies. The emerging wireless technologies are enablers that can be applied to solve many of the wellness challenges, e.g., through the clever combination of wireless radio and smart buildings. Moreover, radio systems are less sensitive to visibility conditions to operate appropriately. Therefore, they naturally mitigate possible privacy concerns that may arise as compared to the camera- or the visible light-based systems where people are "observed" directly through image data or under visible conditions.
The wireless radio-based assisted living can be achieved through the passive detection, the localization and the posture identification of humans. Here "passive" indicates that the assisted individual needs not to wear or carry any additional devices, i.e. "device-free". The existing passive systems employ the time of arrival, the angle of arrival, the received signal strength (RSS), the complex channel state information of radio waves to perform localization. For example, fingerprinting, a localization technique based on RSS measurements, consists of an offline phase to build a database from surveyed signals at known positions. The process is labour intensive and is not robust against changes in physical environment. Alternatively, in multiple-input multiple-output (MIMO) systems, antenna arrays with many elements provide sufficient spatial resolution to discern signals coming from different directions, while wideband provide delay resolution to separate multiple copies of these signals in time. The temporal-spatial-delay domain profiles contain information on human form-factors as well as on surrounding objects. However, it is challenging to sort out human-relevant information.
1C2: Workshop 3: Advancements in 5G Antennas and Emerging 6G Antenna Technologies
Chair: Manabu Yamamoto (Hokkaido University, Japan)
Speaker: Prof. Dr. Wonbin Hong (Pohang University of Science and Technology, Korea)
Abstract
The advent of millimeter-wave and sub-Terahertz for wireless, civilian applications have spurred unprecedented opportunities and challenges within the wireless society. Expanding the technological footprint of millimeter-wave and sub-THz antennas and propagation for Beyond 5G/6G cellular, access and infrastructures are expected to introduce unprecedented challenges. Practical design considerations and potential novel solutions related to the realization of millimeter-wave and sub-THz antennas with beamforming capabilities are discussed in detail.
This workshop attempts to share and discuss the current and emerging challenges surrounding millimeter-wave based 5G antenna systems and the upcomming 6G sub-Terahertz antenna technologies based on realistic considerations and contraints. The workshop will assess the future direction of mobile antennas and RF circuits for high mobility devices such as future smartphones and data terminals using a holistic approach Afterwards, a series of detailed demonstrations will be discussed.
1D2: Workshop 4: The Design of Millimeter-Wave Wideband Multi-Polarization Antenna Array
Chair: Kunio Sakakibara (Nagoya Institute of Technology, Japan)
Speaker: Prof. Dr. Ying Liu (Xidian University, China)
Abstract
With the rapid development of wireless communication, the current fourth-generation (4G) wireless cellular system is challenging to satisfy the continuous growth of wireless traffic demands. Millimeter-wave (mmWave) band has abundant spectrum resources, and a large number of studies on the fifth-generation (5G) wireless communication show that mmWave technology will become the key to the improvement of data transmission rate and capacity in the future.
In this talk, some of our recent work in mmWave wideband multi-polarization antenna array will be introduced. A broadband dual-polarized end-fire mmWave antenna array with a complete GND for 5G communication terminals is presented. The H-P and V-P radiation performance are realized by using electric dipole and SIW cavity, respectively. The measured results show that the impedance bandwidth is 24-29.5 GHz (20.6%). Then, a dual-band dual-circularly polarized magneto-electric dipole antenna array for full-duplex communication systems is presented. The proposed array can simultaneously achieve left-hand circular polarization (LHCP) around 20 GHz and right-hand circular polarization (RHCP) around 30 GHz with a low loss feed network using the printed ridge gap waveguide (PRGW). Finally, the talk will end with the future development trend of mmWave wideband multi-polarization antenna array.
1E2: Workshop 5: Circularly Polarized Antennas: Design and Measurement techniques
Chair: Takafumi Fujimoto (Nagasaki University, Japan)
Speakers: Prof. Dr. Takeshi Fukusako (Kumamoto University, Japan)
Abstract
Circular polarization is an attractive polarization for many types of wireless telecommunications, such as satellite communication, RFID, etc. There are always strict requirements for circularly polarized (CP) antennas, such as broadband, small size, slim shape of designs, low cross-polarization in a wide radiation range of azimuth, etc. Also, designing CP antennas with such challenging performances are attractive for antenna researchers and designers. In this workshop, some design techniques for such applications and requirements are organized. In addition to this, some measurement techniques for essential parameters in circularly polarized antennas, such as axial ratio, gain measurement, will be summarized. In this opportunity, we would like to think of antennas with a point of view of polarization.
