MICROSTRIP PATCH ANTENNA FOR TRANSMISSION/RECEPTION HAVING HIGH GAIN AND WIDEBAND, AND ARRAY ANTENNA WITH ARRAY OF SAME

摘要

PROBLEM TO BE SOLVED: To provide a microstrip patch antenna for transmission/reception having high gain and wideband for increasing a bandwidth and a gain.;SOLUTION: The microstrip patch antenna for transmission/reception having high gain and wideband includes: a first patch antenna layer that includes a ground plane and a first dielectric layer, for radiating an energy supplied from transmitting feeding part electrically coupled with a first radiation patch located on one face of the first dielectric layer and supplying the energy to a receiving feeding part electrically coupled with the first radiation patch, wherein the energy is supplied by electromagnetic coupling of first and second parasitic patches; a second patch antenna layer that includes second and third dielectric layers and the first parasitic patch, for radiating signals through the first parasitic patch arranged in between the second dielectric layer and the third dielectric layer; and a third patch antenna layer that includes fourth and fifth dielectric layers and the second parasitic patch, for radiating signals through the second parasitic patch arranged in between the fourth dielectric layer and the fifth dielectric layer.;COPYRIGHT: (C)2005,JPO&NCIPI
