A 77-GHz FMCW MIMO Radar Employing a Non-Uniform 2D Antenna Array and Substrate Integrated Waveguides

In state-of-the-art frequency-modulated continuous-wave (FMCW) multiple-input multiple-output (MIMO) radar systems, antennas are usually designed based on microstrip technology. They are arranged in uniform arrays such that the synthesized virtual array maximizes the angular resolution. This paper presents the design of a 77-GHz FMCW MIMO...

Conformal antenna array for ultra-wideband direction-of-arrival estimation

The design and full-wave analysis of an antenna system for ultra-wideband radio direction finding applications is presented. The elliptical dipole antenna is selected as antenna element due to its robust circuital and radiation properties. The influence of the conformal deformation on the antenna performance has been studied in details. A...

Design of a sparse irregular array for beyond 5G base stations

New generations of mobile communications are much more demanding in order to provide critical real-time services and extremely fast connections that have become feasible with 5G. A wider spectrum is needed to achieve such high data rates and millimeter-wave frequencies are used for this purpose. Adaptive beamforming is applied at base stations...
