Abstract
A printed antenna comprises an elongate first dipole half element provided on one side of a dielectric substrate. The first dipole half element is end-fed via a microstrip transmission line. A second dipole half element is provided on the opposite side of the dielectric substrate. The second dipole includes first and second elongate elements disposed one on each side of the longitudinal axis of the first dipole half element as viewed through the substrate. The first and second elements are a quarter of a wavelength long and are parallel to the first dipole half element. A ground plane on the second side of the substrate is coupled to the first and second elongate elements at a distance from a free end of the first dipole half element corresponding substantially to a quarter wavelength of the frequency of interest.
