Abstract
Disclosed is a multiple band antenna assembly for communicating electromagnetic radiation. An antenna element stack is constructed of a plurality of elliptical lamina antenna elements mutually separated by layers of dielectric material, and separated from a ground plane by dielectric material. The antenna assembly is coupled through a feed line in contact with the top antenna element. A conductor joins the remaining antenna elements to the ground plane. Each individual antenna element is operable for communication reception and transmission within a frequency band determined by the size of the particular antenna element. The antenna elements are arranged in order of decreasing size with the largest antenna element closest to the ground plane. The sizes of the antenna elements may be selected to provide electromagnetic radiation communication over several distinct frequency bands, or to connect the individual bands into a broad band.
