Speech Title: Antenna Solutions and Analysis for Commercial 5G mmWave Antenna-in-Package (AiP) Designs

Abstract: This presentation will explore the latest trends in 5G millimeter-wave (mmWave) antennas and address the challenges encountered by engineers in this field. To enhance the audience's understanding of mmWave array antenna design within the framework of commercial Antenna-in-Package (AiP) systems, we will examine a series of commercial mmWave AiP designs, starting with the QTM 052. The discussion will explore the design techniques adopted in these solutions and compare them with recent developments in academic research. Finally, the presentation will conclude with a brief outlook on future 5G mmWave (FR2) and 6G communication.

Speech Title: Millimeter Wave Signal Propagation in Indoor Environment and Underground Mine

Abstract: With a huge spectrum of 5–7 GHz allocated as an unlicensed band worldwide, the 60-GHz millimeter wave frequency range has become attractive for future indoor networking. Very high data rates can be reached (on the order of several Gbps) because of the large available spectrum. With low interference with neighboring networks due to the oxygen resonance around 60 GHz, it becomes feasible to control mining machinery and implement underground communications by using wireless sensors. Modelling 60 GHz millimeter wave signal propagation in indoor environment and underground mine is of vital importance for realizing the above goals. Most of published channel modeling studies in the 60 GHz still make efforts to evaluate the heuristic diffraction coefficients around corners for relaying the signal while denying surrounding deflecting obstacles (DOs) and considering them as noise sources. Few measurements of radio propagation in underground mines have been carried out for the MIMO-mmW systems, including the effect of miners’ activity. In this presentation, the importance of the presence of deflecting obstacles (DOs) for indoor wireless local area network (WLAN) applications in the 60 GHz band is evaluated, the propagation characteristics of a MIMO-mmW system within an underground mine environment is discussed, with the effect of miners’ activity being considered.

Speech Title: Multi-Function Multi-Beam Reflectarray Antenna for Sub-Terahertz Applications

Abstract: A single-layer-substrate dual-band multi-beam reflectarray antenna based on polarization selection technique for sub-terahertz (sub-THz) applications is proposed in this talk. The antenna element consists of two primary ring components (outer and inner) that are orthogonally nested to achieve dual-band characteristics. The outer component is a split ring structure aligned along the y-axis, designed to excite X-polarized radiation through a pair of arc-shaped phase shift lines extending from the sides of the ring. The inner component, located within the outer ring, comprises two small arc-shaped microstrip patches connected vertically by a straight-bar microstrip line, resulting in Y-polarized radiation. Furthermore, the digital coding metasurface together with the single- and multi- focus phase compensation techniques , enables the antenna array to achieve four-beam radiation and dual-beam scanning in the lower and upper frequency bands. Measured results show a very wide elevation angle of up to 104°and a high aperture efficiency of 49.2% at the lower frequency of 135 GHz. At the upper frequency of 170 GHz, a low scanning loss of 1.6 dB and a high aperture efficiency of 29% are realized. Additionally, high peak gains of 19.7 dBi and 26.3 dBi are obtained for the respective bands. Therefore, the proposed sub-THz reflectarray antenna presents itself as a promising candidate for future 6G point-to-multipoint communication systems, offering large capacity, wide coverage, and high-resolution scanning capabilities.

Speech Title: Wi-Fi Signal Gesture Recognition Based on Multimodality

Abstract: With the development of technology, various gesture recognition devices and technologies have emerged to meet people's various needs. Traditional gesture recognition methods are relatively cumbersome and require wearing data gloves. At the same time, the technology based on computer vision needs to recognize that the target is always within sight. Therefore, we proposes a gesture recognition method based on multimodal Wi-Fi signals, and optimizes the gesture recognition methods from devices and technologies to overcome the problems in traditional recognition methods. Specifically, we first built a Wi-Fi signal data acquisition platform based on the Atheros network card, and the packet loss rate is less than 0.1%. Then, frame extraction is carried out for the video signal, and the T3D network based on DenseNet is used for video recognition. The video recognition rate reaches 95.0%. Finally, the above video data is extended to Wi-Fi signal, gesture recognition is performed jointly with CNN and GRU. The tests show that the gesture recognition rate of proposed scheme is 88.2%.
