An all-metal, broadband, dual-polarized Vivaldi array antenna was designed and fabricated. The structure of the proposed antenna comprised a resonant cavity and tapered fins that contacted the ground plane directly, allowing the connection of a balun

In this paper, we propose an optimization method for obtaining beam curve which minimize the phase errors of Rotman lens. This method is based on idea that 3 path lengths from a beam port through equal phase points, which consist of the center point

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 by moving off-axis focal points along a beam curve. It ensures additional
