Super broad band ladder-shape floor printing single pole antenna

This invention relates to a super-wide band plane monopole antenna which is processed by printing a monopole antenna plate, a coplanar metal floor and a built-in feed wire on a dielectric plate, among which, the monopole antenna plate is an elliptic, round or a ring adhering sheet, the built-in feed wire is a coplanar wave guide conduction band sheet, the coplanar metal floor is a ladder metal adhering sheet divided into right and left two sheets and adhered on both sides of the conduction band adhering sheet. The antenna has fine wide band property7 realizing stationary wave bandwidth over 15 frequency multiplication and gets-2-5db gain.
