New Configurations of Low-Cost Dual-Polarized Printed Antennas for UWB Arrays
Figure 1
Geometry of the radiating element under analysis in Section 3, based on four rhombic coplanar elements printed on the top of a three-layer configuration. (a) 3D view of the antenna. (b) Upper view of the structure. Lowest substrate: thickness mm, relative dielectric constant , loss tangent (duroid RT 5880 Rogers). Middle substrate thickness mm, relative dielectric constant , loss tangent (FR4 epoxy). Uppermost substrate thickness mm, relative dielectric constant , loss tangent (RT 5880 Roger). Overall unit-cell dimension mm. Geometrical parameters of the patches: mm, mm, mm, mm, mm, mm, mm, mm, mm, and mm ( and are the width and the length of the th patch, resp.). Diameter of the probe mm.
