MULTI-BAND MICROSTRIP ANTENNA HAVING amp;lambda;/4 PARASITIC ELEMENTS STACKED THEREON

摘要

A multi-band microstrip antenna having λ/4 parasitic elements stacked thereon according to the present invention comprises: a ground plane (100) for performing a grounding function; a quadrangular patch (200) having part of one diagonal cut on the ground plane (100); λ/4 parasitic elements (300-1, 300-2, 300-3, 300-4) in the shape of an inverted L stacked on the patch (200); and a coaxial probe connected to a feeding point (400) for feeding a designed antenna. Therefore, the λ/4 parasitic elements maintain the characteristics of a low profile together with the characteristics of multiple bands such as GPS L1(1.575GHz) and L2(1.227GHz) bands via coupling with a microstrip patch antenna.;COPYRIGHT KIPO 2016
