Advanced Millimeter-Wave and Microwave Transceivers for FMCW Radar and 5/6G Beamforming Systems

Dear Colleagues,

Recent advances in mm-wave and microwave IC technologies are rapidly transforming high-resolution sensing and high-capacity wireless communication systems. The convergence of FMCW radar, MIMO signal processing, and 5G/6G beamforming has created integrated sensing-and-communication (ISAC) system able to deliver high spatial resolution, low latency, and robust environmental awareness. Modern mm-wave transceivers—enabled by CMOS, SiGe, and III-V semiconductor technologies—now support compact phased arrays, wide instantaneous bandwidth, precise frequency synthesis, and digitally assisted calibration, making them highly suitable for autonomous vehicles, robotics, indoor positioning, smart manufacturing, and next-generation cellular networks.

This Special Issue aims to gather contributions on advanced architectures, circuits, algorithms, and system-level innovations that push the boundaries of mm-wave sensing and communication. Topics include integrated phased-array transceivers, digitally controlled beamforming, high-linearity RF front-ends, multi-antenna FMCW radar, and joint radar-communication frameworks. We invite original research papers, reviews, and application-oriented studies addressing both theoretical and practical challenges in next-generation mm-wave radar and beamforming systems.

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. 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.
