Abstract
An antenna system for use in cellular and other wireless communication includes a dual polarized compact antenna array. In one embodiment, the antenna system includes four T-shaped dipole antenna elements mounted on a ground plane, forming a side of a square shaped array. In another embodiment, the antenna system includes seven T-shaped dipole antenna elements mounted on a ground plane to form two side by side square arrays, wherein the square arrays share a common T-shaped dipole antenna element.
Claims10
A dual polarized antenna array comprising:
- a ground plane;
- a first and a second T-shaped dipole antenna element mounted along a first axis of the ground plane;
- a third and a fourth T-shaped dipole antenna element mounted along a second axis of the ground plane wherein the first and second axes are mutually parallel,
- a fifth, a sixth, and a seventh T-shaped dipole antenna element mounted along a third, a fourth, and a fifth axis, respectively, of the ground plane, wherein the third, fourth and fifth axes are mutually parallel with one another and orthogonal to the first and second axes, the sixth T-shaped dipole antenna element being positioned between the first and second T-shaped dipole antenna elements, and the first and second T-shaped dipole antenna elements being positioned between the fifth and seventh T-shaped dipole antenna elements;
- a first power divider coupled to the first, second, third, and fourth T-shaped dipole antenna elements;
- and
- a second power divider coupled to the fifth, sixth, and seventh T-shaped dipole antenna elements.
