ULTRA WIDE BAND MONOPOLE INTERNAL ANTENNA

摘要

An ultra wide band monopole internal antenna is provided to control a bandwidth of the antenna by controlling the width of a first stub. An ultra-wideband monopole built-in antenna includes a dielectric substrate(100), a ground unit(102), a feeding unit(104), a first stub(106), a radiator(108) and a second stub(110). The ground unit is formed in a partial domain of the dielectric substrate. The feeding unit is separated from the ground unit as much as the predetermined distance and is formed in the dielectric substrate. The first stub is combined in one end of the feeding unit. The first stub is perpendicularly formed in the dielectric substrate. The radiator is combined with the radiator. The radiator is formed in the dielectric substrate. The second stub is combined with the radiator. The second stub is perpendicularly formed in the dielectric substrate. The radiator has the shape of the rectangular plate. The width of the first stub is smaller than the width of the radiator.
