The present invention provides a planar antenna having a scalable multi-dipole structure for receiving, and transmitting high-frequency signals, including a plurality of opposing layers of conducting strips disposed upon either side of an insulating (dielectric) substrate. The dipoles are bifurcated between sides of a substrate on which the dipoles are disposed. A feed line is balanced to a co-axial cable and feeds one half of the bifurcated dipoles, and an independent feed line is connected to the other half of the bifurcated dipoles. Sets of the dipoles are arranged symmetrically around a center axis of the feed lines. The sets of dipoles are in series with other sets of dipoles. The antenna is ideally suited for operation in the 5.15-5.35 GHz RF band. |
