ULTRA WIDE BAND ANTENNA FOR INCREASING A RADIATION PATTERN AND A GAIN THROUGH A PARASITIC PATCH AND INCREASING BANDWIDTH OF REFLECTION COEFFICIENT

摘要

PURPOSE: An ultra wide band antenna for increasing a radiation pattern and again through a parasitic patch is provided to increase the property of reflection coefficient in a UWB communication service frequency band by forming first and second metal patterns.;CONSTITUTION: A first metal pattern(111) is formed in the upper side of a dielectric substrate(110). The first metal pattern has a quarter-ellipse shape. A feeding unit(115) forms a feeding path of the first metal pattern. The feeding unit is extended from the first metal pattern. A second metal pattern(121) is formed in a lower side of the dielectric substrate. The second metal pattern is symmetrical to the first metal pattern. A ground unit(125) of a conductive material is separated from the second metal pattern.;COPYRIGHT KIPO 2013
