Abstract : A coupled multilayer microstrip antenna having an upper and a lower microstrip element tuned to the same frequency, and separated from each other by a dielectric substrate. The pair of elements is located over a suitable ground plane and separated from the ground plane by a second dielectric substrate. The upper element is the driven element which is directly coupled to the feed line while the lower element is parasitically coupled to upper element. The lower element cancels the image field as seen by the upper element providing enhanced radiation at angles closer to the ground plane. (Author)
