Abstract (en)
[origin: EP0651458A1] The invention relates to a method of manufacturing a planar antenna, operating at a frequency of a few GHz, comprising at least one circuit layer, in which, for each circuit layer, a selective metallisation is produced on a support (10) of organic material, having a low dielectric constant, less than 2.5, and low losses, less than 10<-3> by deposition of a layer (11) of conducting material over all or part of at least one surface of the said support, thus making it possible to define the conducting parts of this circuit, possibly after deposition of an intermediate layer (12) intended to improve the surface state of the said support. The invention relates particularly to a planar antenna operating at such a frequency. Application particularly to the field of telecommunications with mobile units. <IMAGE>
