Dear Colleagues,

Wireless identification of people and physical objects has enabled them to become smartly connected, thus opening the door for the development of numerous field applications, such as healthcare, structural health monitoring, disaster monitoring, logistics, social networking, smart environments, security services, and many more. While many applications rely on passive chipped tags, chipless tags play a complementary role particularly in harsh environments, as well as for indoor tracking and localization. In this regard, the use of novel manufacturing techniques enables the realization of robust tags able to withstand harsh conditions such as under high temperatures, ionizing radiation, corrosive gases, and strong vibrations. The tendency toward higher frequencies in the millimeter wave (mm-Wave) and terahertz (THz) ranges allows for wider bandwidths and lower multipaths by using high-gain antennas with small footprints, which contribute toward increasing the ranging capabilities while reducing clutter.  Moreover, recent developments in smart sensing with low cost and energy-autarchic systems is of great scientific and technological interest.

This Special Issue will also focus on solutions to enlarge the coverage of current radio frequency identification (RFID) solutions aiming at pedestrian and cyclist safety in outdoor automotive scenarios.

We invite researchers and practitioners to submit high-quality contributions that will stimulate continuous efforts to improve RFID technology in the context of the following non-exclusive and indicative list of research topics:

• Millimeter wave (mm-Wave) and terahertz radio frequency identification (THID) tags
• RFID indoor and outdoor localization systems
• Solutions for clutter and multipath suppressions
• RFID system simulations, measurements, and modeling
• Nonlinear RFID
• Wireless body area networks (WBANs) based on RFID systems
• RFID data fusion
• RFID technology for smart healthcare, environments, and sensing
• RFID employment in facing pandemic outbreaks
• Novel wireless sensor systems and networks
• RFID emerging technologies and applications

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Electronics is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
