This presentation will introduce several new design trends and applications for RFID tags and NFC antennas. The recent advancements in the design of RFID tags for conductive (metal) surface will be highlighted with examples working in the ultra-high frequency (UHF) bands, and a variety of design solutions for increasing the circular polarization (CP) bandwidth and improving the reading range of a UHF RFID tag with CP radiation will be demonstrated with experimental results. In recent years, severe problems and impacts have been encountered by the mobile device industry owing to the use of metal-cover on smartphone, especially when the NFC application is now a prerequisite requirement. To allow the integration of NFC antenna into a metal-cover smartphone, this presentation will introduce a few practical examples that highlight the recent design methodologies for improving the reading range, as well as mitigating the eddy current effects induced on the metal-cover by the NFC coil. Lastly, this presentation will also feature several practical small-size WLAN antennas that can be built into the laptop and notebook with full metal-casing.

Micro-Antennas for Ubiquitous IOT Devices
Prof. Terry Ye
Dept. of Electrical and Electronics Engineering (EEE)
Southern University of Science and Technology (SUSTech), China
Internet-of-Things (IOT) is regarded as the next paradigm shift in technology after the Internet. Many IOT devices, such as RFID and wearable electronics, had already prevailed in people’s daily life. Future IOT devices are promised to be built into everyday objects, where “things” are connected in a ubiquitous network.
Different from traditional wireless transceiver devices, IOT devices pose many new technical challenges in its antenna designs. In this presentation, we will use RFID systems as examples to analyze the unique challenges for antenna designs from IOT deployment. First, RFID devices have to be attached, or embedded inside the host objects where the properties of the host materials will detune the RF performance significantly. Second, RFID antennas are not standalone in the air, in most cases they have to be packed tightly in close range (like a stack of books or a pallet of boxes), coupling and shielding between hundreds of closely packed IOT devices will certainly degrade each other’s transmission, special RF enhancement techniques have to be explored. Third, as the RFID tag becomes part of the object it attaches to, new materials are explored to build RFID antennas, such as fabrics or conductive inks, it not only reduces the cost of RFID overhead, the antennas can also be decomposed during recycling process to reduce the environmental hazard.
Although these challenges are coming from RFID deployment, the problems are universal to all IOT micro-antenna designs. Designers cannot only rely on the traditional antenna design techniques, they need to have a comprehensive consideration of different factors, including EM radiation, chip bonding, ambient conditions and materials and cost overhead, etc.
As cost and performance trade-off is the crucial factor in IOT adoption, the presentation will particularly focus on the balancing between cost-reduction, performance optimization as well as technical feasibility of mass-deployment of the ubiquitous IOT systems.

RFID has been invented for decades and it has a wide scope of applications, such as electronic payment, asset management and retail sales, transportation and logistics, and so forth. Driven by latest UHF RFID technologies, lots of smart services are developed in the past few years, namely unmanned supermarket, unmanned library, electronic toll collection (ETC) etc. Nevertheless, RFID still has a tremendous potential in the topics of Internet-of-Things (IoT) and smart city. In this talk, we will focus on the handheld RFID reader from typical RFID system and present the recent advance of antenna for low profile handheld RFID reader design. The proposed antenna can radiate its main beam in parallel with its plane meanwhile maintaining a planar configuration, which is advantageous for low profile RFID handheld reader as a welcoming tool for emerging smart services.

Radio frequency identification (RFID) technology are being rapidly developed in recent years and the applications have been widely found in Internet of Things (IoT) such as service industries, distribution logistics, manufacturing companies, and product-flow systems. Antenna design for readers and tags is one of the key factors in RFID systems. The optimized tag and reader antenna designs will greatly benefit to RFID systems with longer reading range, better detection accuracy, lower fabrication cost, and simple system configuration and implementation. This talk will start with a brief introduction to RFID systems which may be active, passive, or semi-active systems, and operate at LF, HF, UHF, or MW bands. Then the key considerations related to the antenna design for tags and readers will be addressed from system perspectives. After that, the advancement of RFID antenna designs by the team from Institute for Infocomm Research/National University of Singapore will be highlighted, in particular, the specific challenges for antennas in the HF near-field and UHF near/far-field systems. The important engineering factors such as environmental effects vs. co-design methodology, size constraints, cost constraints, and UHF near-field reader antenna coverage are presented with corresponding practical design cases.
