Recent Advances in Front-End Designs for Sensors and Wireless Networks

Dear Colleagues,

In response to the continuously-increasing need for the connectivity of wireless devices, driven by the increase in the number of applications and the number of connected wireless devices and sensors, the Internet of Things (IoT) concept has been introduced as a model to build more intelligent and interconnected cities. New wireless and sensor communication standards and protocols are being studied in this perspective, which will impose increasing constraints in the design of such communication systems.

In particular, the hardware implementation of the RF front-ends of wireless and sensor communication systems is becoming more and more challenging. Integrability, low-cost, low-power consumption, and reconfigurability all become equally important and essential in these designs. Reconfigurable and broadband implementation suitable for multi-band, multi-standard, and software defined and cognitive radios are becoming more desirable than ever before. Ultra-low power or even autonomous RF sensors and receivers are becoming a must for the next generations of RF front-ends. Power harvesting is becoming an essential technique to provide all or most of the energy requirements for these RF front-ends.

This Special Issue aims to highlight the recent advances in RF front-end designs for sensors and wireless networks, which would be used as a building block for the IoT. Topics include, but are not limited to:

• Ultra-low power and autonomous RF sensors and receivers
• Reconfigurable and smart RF front-ends
• Multi-band, multi-standard RF front-ends
• Broadband RF front-ends
• Low-cost highly integrable RF front-ends
• Energy harvesting techniques

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors 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 2600 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.
