Structure of double-fed Dual Resonance microstrip patch antenna

摘要

PURPOSE: An antenna structure is provided to achieve an improved convenience for a mobile communication service by reducing the size and weight of the antenna and allowing the antenna to be readily installed in any place. CONSTITUTION: An antenna structure comprises the first dielectric layer(15) having a rectangular patch type radiation element(11) coupled onto the upper surface of the first dielectric member, and which has a micro strip feeder line(12) formed at a surface of the radiation element so as to perform micro strip feeding operation; an air layer(17) formed beneath the first dielectric layer so as to increase frequency bandwidth; a conductive plate(13) formed beneath the air layer, and which includes an aperture(18) formed at the interior of the conductive plate; and the second dielectric layer(16) formed beneath the conductive plate, and which has an opening coupling feeder line(14) formed at the lower surface of the second dielectric layer. The feeder line is arranged to be perpendicular to the opening of the conductive plate.
