Reconfigurable Antennas

Dear Colleagues,

It is my great pleasure to announce this Special Issue on “Reconfigurable Antennas”. Modern telecommunications systems, such as radio links, radars, and mobile devices, require antennas that are able to operate in different complex environments. In particular, new mobile smart phones, offer different services that require a high degree of reconfigurability in spite of the limited dimensions of the devices. The 5G generation devices offer, in addition to usual voice and other services of standard previous systems, ultra-broadband Internet connection, IP telephony, mobile web access, gaming services, and other interesting multimedia application (such as high-definition television). In such a framework, the design of a suitable radiating system could play a key role in the design of new generations telecommunication systems. The antenna system for these devices must be light, cheap and able to keep the devices performances to high levels and in any environments. In such a framework, the use of reconfigurable antennas with fully adaptive properties is mandatory to dramatically improve the performances of a telecommunication system. Such kind of antennas are commonly used in several fields of applications, such as airport surveillance, missile detection, and tracking. The objective of this Special Issue is to provide an overview of the current research on “Reconfigurable Antennas”, highlight the latest developments and innovations, and identify new challenges and opportunities of applications.

Suggested topics include, but are not limited to:

• Fully adaptive array,
• phased arrays,
• MIMO antennas,
• switched beam antennas,
• multi frequency antennas.

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.
