Abstract
An antenna is disclosed with a first Z-shaped strip resonant element disposed in a first plane. The first strip resonant element has first and second identical sized and shaped, parallel, longitudinal strip segments. The first strip resonant element also has a third segment which connects diagonally opposite ends of the first and second strip segments. The antenna also has a second Z-shaped strip resonant element disposed in a second plane that is parallel to the first plane. The second strip resonant element has fourth and fifth identical sized and shaped, parallel longitudinal strip segments. The second strip resonant element also has a sixth segment, having identical dimensions and an identical shape as the third segment, which connects diagonally opposite ends of the fourth and fifth segments. The second Z-shaped strip resonant element is disposed in the second plane so that the sixth segment overlies said third segment and so that said first, second, fourth and fifth segments overlie a rectangle.
