Abstract
A phased array antenna(10) includes a current sheet array (20) on a substrate (23), at least one dielectric layer (24) between the current sheet array and a ground plane (30), and at least one conductive plane (25) adjacent to the substrate for providing additional coupling between adjacent dipole antenna elements of the current sheet array.
Claims28
A phased array antenna, comprising:
- a substrate and an array of dipole antenna elements thereon, each dipole antenna element comprising a medial feed portion and a pair of legs extending outwardly therefrom, adjacent legs of adjacent dipole antenna elements including respective spaced apart end portions;
- at least one dielectric layer between the substrate and a ground plane;
- and
- at least one conductive plane adjacent to the substrate for providing additional coupling between adjacent dipole antenna elements.

1 more element
A method for making a phased array antenna comprising:
- providing a substrate;
- forming an array of dipole antenna elements on the substrate to define the phased array antenna, each dipole antenna element comprising a medial feed portion and a pair of legs extending outwardly therefrom, and positioning and shaping respective spaced apart end portions of adjacent legs of adjacent dipole antenna elements to provide increased capacitive coupling between the adjacent dipole antenna elements;
- providing a conductive plane adjacent to the array of dipole antenna elements to provide further capacitive coupling between the adjacent dipole antenna elements.
