MICROSTRIP ANTENNA USING L-SHAPED PLATES

摘要

A microstrip antenna using L-shaped plates is provided to miniaturize a linear polarization and circular polarization microstrip antennas by using the L-shaped plates. In a microstrip antenna using L-shaped plates, a flat patch(10) has a rectangular shape. A plurality of plates(20) having an L-shape with a predetermined width is attached to a lower side of the flat patch(10) with the same gap. And, a dielectric material(30) filling an empty space formed between the plates(20) makes each plate(20) to maintain the circular shape.
