Sensors and Digital Modulation in Modern Life: Antenna Design and Massive MIMO Systems

Dear Colleagues,

Worldwide, many new wireless communication applications are presented every year. A large portion of these applications requires high levels of reliability and speed. In recent years, Massive MIMO (mMIMO) techniques have received considerable research interest from both academia and industry and are being employed as a key enabling technology for 5G more and mre often and are the subject of intensive research investigations for the upcoming 6G system in order to achieve those requirements. However, the aesthetic needs and size restrictions that require the antenna arrays to become smaller have introduced some serious drawbacks due to the mutual coupling between the antenna elements in mMIMO arrays. To combat the mutual coupling effects, the antenna research community has introduced numerous techniques that utilize artificial materials, special signal filtering designs, and many others techniques. However, these designs are mainly focused on traditional MIMO systems. Therefore, as a consequence of the extremely large number of antenna elements in mMIMO systems, it is mandatory to develop cost-effective antenna arrays operating in the sub-6 GHz and millimeter wave bands region to deploy increasing numbers of antennas in fixed physical space for both the base station and user terminals, including antennas installed on vehicular platforms.

This Special Issue addresses all types of antenna arrays designed for Massive MIMO systems at the base station and/or user terminals and their performance metrics, such as system capacity, throughput, CSI, power efficiency, and antenna selection, in realistic propagation environments.

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. 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.
