Radio frequency (RF) antenna array systems are of increasing interest for wireless communications, such as remote sensing, radars, satellite receivers, etc. They can be implemented in a wide range of communication applications for electronically scanning the beam pattern of the antenna arrays. The beam patterns characterize the important specifications of the antenna arrays, including spatial direction, gain, beamwidth, etc. Apart from the RF antenna arrays, ultra-wideband (UWB) radio-based antenna array systems are also attractive, for example, for radar and short-range communications, since they exploit very narrow pulses which result in covering extremely large bandwidths and thus achieving high-range resolutions and high data rates.
Antenna arrays allow for the reconfigurability and electronically scanning or reshaping of beam patterns. This technique is known as beamforming. In fact, beamforming is a form of spatial filtering in which elements in an antenna array are combined so that received signals at one particular direction are enhanced, while attenuating or nullifying unwanted interfering signals coming from other directions as much as possible.
The scope and purpose of this Special Issue is to publish papers in the specific area of ultra-wideband antenna array systems dealing with the theory, design, and experimental verification of the transistor-level integrated circuits. Antenna array beamforming systems are attracting increasing attention and have a broad application in radars, high-resolution imaging, and communications. This Special Issue covers research topics such as analog and mixed-signal circuits and systems, tunability techniques of circuits and systems, modeling and design techniques, and control schemes for the realization of the antenna array beamforming systems.

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. 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 2200 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.
