Smart Antennas and Systems for 5G and Beyond: Latest Advances and Prospects, 2nd Edition

Dear Colleagues,

We are pleased to announce the second edition of the successful Special Issue “Smart Antennas and Systems for 5G and Beyond: Latest Advances and Prospects”.

The development and deployment of modern wireless networks—such as 5G, upcoming 6G, and emerging Wi-Fi standards—are enabling a wide range of applications with increasingly stringent requirements. In the near future, it is expected that 5G FR1 networks will be widely deployed, 5G FR2 networks will be developed, numerous satellite constellations will be launched, and the foundations of 6G will be established. All these developments are part of the promise of offering higher data rates and negligible latency and will eventually lead to universal connectivity. The aim is to implement a cellular network in which sensors, appliances, mobile devices, and autonomous devices (such as cars or industrial elements) can interact with each other and meet different requirements based on their nature. In addition, 5G will allow for the coexistence of multiple users requiring high data rates. The development of smart or adaptive antennas plays a key role in meeting the stringent requirements posed by these new communication scenarios.

The objective of this Special Issue is to highlight the latest advancements in smart antenna design, with the ultimate goal of advancing the aforementioned applications and expanding the horizons of this captivating field. We warmly welcome researchers and industry professionals to contribute original research papers focusing on various topics, including, but not limited to:

• Multibeam antenna technologies.
• Plane-wave generators.
• Reconfigurable intelligent surfaces.
• Metamaterial-based antennas.
• Wearable antennas.
• Millimeter-wave (mmWave) and THz antennas.
• Millimeter-wave (mmWave) and THz cooperative relays.
• Compact antennas for massive MIMO.
• Sub-THz channel sounders using phased-array and virtual-array solutions.
• Antennas for the Internet of Things.
• Antennas and transceivers for full-duplex communication.
• Mobile UE tracking antennas for LEO satellite systems.
• Advanced 5G mmWave antennas for mobile industrial elements.
• Miniaturized UWB and mmWave antennas for novel 6G in-X subnetwork scenarios.
• Antennas for wireless power transmission and harvesting.

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.
