| 摘要 |
The present invention provides a planar antenna (1) 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 a dielectric substrate (5). The dipoles (2,4,6,8) are bifurcated between sides of the substrate (5) on wich the dipoles are disposed. A feed line (12) is balanced to a coaxial cable and feeds one half of the bifurcated dioles (2B,4B,6B,8B), and an idependent feed line (10) is connected to the other half of the bifurcated depoles (2A,4A,6A,8A). Sets of the dipoles are arranged symmetrically around a center axis (30) of the feed lines (10,12). 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. band.
