Abstract: In this article, a high-gain millimeter-wave (mmW) slot antenna array is proposed based on a novel two-dimensional (2-D) epsilon-near-zero (ENZ) feeding network. This ENZ feeding network ...
Abstract: Two-dimensional (2D) direction-of-arrival (DOA) estimation using sparse arrays shows advantages in reducing hardware costs and enhancing degrees-of-freedom. However, most current studies ...
