Abstract (en)
[origin: WO9815030A1] The microstrip antenna consists of a radiating metallic portion, laid on a first dielectric substratum (S1), under which a metallic mass plane (GP) is present, in which two non resonant coupling slots (SA and SB) are constructed, in correspondence with MP. Below the metallic plane (MP) there is a second dielectric substratum (S2) under which two metallic feeder lines (LA and LB) are constructed, in correspondence with the relevant slots. The control of the direction of the axis of maximum radiation is obtained either by feeding the two metallic lines with voltages of different phases or in a variant feeding only one line and closing in short circuit the other line in variable position along it.
