In this paper, we present an overview of our recent works on artificial dielectric layers (ADLs), used to enhance the radiation efficiency of planar printed antennas and arrays. The artificial material is realized by introducing planar sub-resonant metallic inclusions in a hos ...
Microwave broadband wide-scan antenna arrays are typically implemented resorting to vertical arrangements of printed circuit boards (PCBs). Here, we propose a planar solution realized with a single multi-layer PCB, with consequent reduction in cost and complexity of the array. It

We propose a radiation concept to realize phased arrays with wideband and wide-scanning performance. The array is based on connected-slot elements that radiate in the presence of artificial dielectric superstrates. The array can be implemented with a single multi-layer printed ci

A Planar Wideband Wide-Scan Phased Array
Connected Array Loaded with Artificial Dielectric Layers
We present a novel concept for wideband, wide-scan phased array applications. The array is composed by connected-slot elements loaded with artificial dielectric superstrates. The proposed solution consists of a single multi-layer planar printed circuit board (PCB) and does not r

In this paper, we demonstrate, at 300 GHz and with integrated technology, the effectiveness of artificial dielectric layers to enhance the front-to-back ratio of printed antennas. This concept was previously proposed at microwave frequencies and using printed circuit board techno

We present an analytical method to model artificial dielectric layers (ADLs) of finite height. Starting from the closed-form solution for the scattering from a single layer under plane wave illumination, the formulation is extended to the multi-layer case, by including the higher

We present an analytical formulation to describe the plane-wave propagation through artificial dielectric layers (ADLs) of finite thickness. The formulation is based on a spectral domain approach derived for connected arrays. An analytical circuit model based on this approach is
