(54) Planar antenna device and a method for providing conductive elements on a substrate


(57) A antenna arrangement is disclosed for use in vehicles and other application where the antenna can be affixed to a surface, e.g. a window. The antenna 10 is formed from 2 square elements 12,13, defined within a rectangle. Additional square elements 17, 18 may be defined within the other square elements. The dimensions may be chosen so as to maximise gain for selected radio frequencies. Also disclosed is a method for providing conductive elements on a substrate, including printing a conductor pattern onto a substrate using conductive ink, and using the deposited pattern as a electrode for an electroplating process.
