Microstrip antenna for circularly polarized waves with predefined resonant frequency and axis characteristic, has dielectric substrate with flat electrode and setting electrode in notch

摘要

The antenna has a dielectric substrate (4) with a flat electrode (2) formed on its surface and an earth electrode on almost the entire other surface. A notch (2a,2b) for retraction and separation is formed on one of the two line intersecting at right angles in the center of the flat electrode in at least one edge of the electrode. A setting electrode (2c,2e) in the notch extends out from the edge of the flat electrode.
