Abstract: PURPOSE: A high gain microstrip antenna is provided to achieve improved gain and directivity of the antenna by arranging dielectrics having a high dielectric constant on the top of the antenna. CONSTITUTION: A high gain microstrip antenna comprises a first dielectric layer(340); a grounding surface(300) formed on the first dielectric layer, and which has a plurality of slots(320); a plurality of feeder lines(310) formed at the lower surface of the first dielectric layer and overlapped with the slots of the grounding surface; a first air layer(350) formed on the first dielectric layer; a plurality of patches(100) formed in the air layer such that the patches transmit electric waves through the feeder lines and the slots; a second dielectric layer(360) formed on the first air layer, and which has a dielectric constant higher than the dielectric constant of the first dielectric layer; a second air layer(330) formed at the lower surface of the first dielectric layer; a metal surface(370) formed at the lower surface of the second air layer; a plurality of T-junctions for distributing electric waves to the feeder lines; and a waveguide for transmitting electric waves to the T-junctions.
