An ultra-wideband (6-18 GHz) phased-array antenna with a beam scanning angle of±28° is
proposed. A step-by-step design procedure consisting of beamforming network (BFN), end …

This letter describes a novel focal curve design method for two-dimensional Rotman lenses.
The proposed design method offers some additional degrees of freedom in the design of …

A broadband high-gain millimeter-wave (mmWave) array beamforming network (BFN)
design, analysis, and implementation based on the Rotman lens antenna array feeding are …

The next generation of wireless networks (5G) employs directional transmission at millimeter
wave (mmW) frequencies to provide higher bandwidth and faster data rates. This is …

In this paper, we propose a refocusing method for minimizing phase errors of Rotman
lenses. The method is based on finding the optimal α, F, and γ minimizing the phase errors …

This paper introduces an improved design method supported by analytical formulas defining
the focal curve of a Rotman lens with reduced worst-case phase-aberrations. The benefit of …

We address the multiobjective optimization of a Rotman lens by means of a recently
proposed method based on the minimization of a properly defined global cost function …
