Wideband RF Front-End Components for Ultra-Wideband (UWB) Applications

Dear Colleagues,

In recent years, wireless communication technology has rapidly developed, and wireless communication services have diversified and complicated. Ultra-wideband (UWB) systems are attracting attention as ultra-high-speed wireless communication technologies. A major feature of UWB communication is that it uses a very wide frequency band compared to conventional wireless systems. The frequency band of UWB communication is available in the microwave band of 3.1 to 10.6 GHz, and in the quasi-millimeter wave band of 22 to 29 GHz. The UWB system is capable of high accuracy position measurement with an error of a few centimeters as well as large volume data transfer. The system using the impulse radio-type UWB (IR UWB) is expected to be applied to material management and safety management in factories, for example.

Application in healthcare is expected for the wireless body area network (WBAN) to the surface of the human body. If a broadband antenna can be used to cover the band of wireless LAN, Bluetooth, ZigBee, etc., and even 5G communication with a single antenna, wireless devices can be significantly reduced in size.

The major topics of interest for this Special Issue include, but are not limited to:

• Ultra-wideband antennas
• Broadband antennas
• Multiband antennas
• Ultra-wideband communication
• Ultra-wideband radar
• Radar applications
• UWB system

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-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.
