RFID and Applications of RF/Microwave Circuits and Systems

Dear Colleagues,

Radiofrequency identification (RFID) and wireless identification are modern technologies with a wide range of applications. Some popular utilizations include indoor and outdoor tracking, sensing, operation of tag-attached objects, human bodies, etc. Wireless identification of people and physical objects has enabled them to become smartly connected. This has led to scientific breakthroughs in various fields of human endeavours including healthcare, health monitoring, disaster monitoring, logistics, social networking, smart environments, security services, etc. Though many applications rely on passive chipped tags, chipless tags have been recently gaining popularity. RFIDs rely heavily on radiofrequency (RF) circuits and components for successful operation. RF falls within the electromagnetic waves, with frequencies ranging from 300 MHz to 300 GHz, which are sometimes classified as microwaves. This frequency span matches the free-space wavelengths of 1 m to 1 mm, in that order. Electromagnetic waves with frequencies varying from 30 GHz to 300 GHz are classified as millimetre-waves due to their wavelengths that fall directly above 1 mm and directly below 10 mm. The RF band falls somewhere beneath the microwave range, though the border in the middle of RF and microwave bands is subjective and adjusts based on the technology established for the development of the band.

The main topics of interest include, but are not limited to, the following:

• Smart connectivity
• Wireless identification
• Localization systems
• Indoor and outdoor sensing systems
• RFID data fusion
• Smart healthcare
• Neural networks and intelligent systems
• Wireless sensors
• Nonlinear RFID
• RF and microwave circuits and devices
• Applications of compressive sensing theory

Authors are invited to submit their latest related research findings for publication. Both regular articles and review papers are welcome.

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. Designs 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 1600 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.
