Abstract: A fixed antenna includes multiple printed board panels, each containing an array of radiating elements where a subset of radiating elements receives a delayed signal from a feed layer. The number of panels is minimized by configuring each array to generate a shaped beam. The shaped beam is produced by non-uniformly spaced elements and non-uniform array element phase shifts.

Abstract: An antenna with an FR-4 dielectric material layer includes at least one metallization layer having metallic dipoles organized into two clusters. Each of the two clusters includes metallic dipoles generally elongated along a common axis to produce signals of specific polarization. Each of the two clusters is oriented orthogonal to the other to produce two separate, orthogonally polarized signals. Each of the two clusters is associated with a dedicated stripline feed, positioned and oriented to maximize gain of the radiating element. Power from each stripline planar feed couples to the metallic dipoles through a dedicated aperture in the stripline ground plane.
