PLANAR ANTENNA

摘要

A planar antenna is provided to adjust a central frequency and a bandwidth of a notched frequency band by adjusting a shape and a length of radiation elements. In a planar antenna, a conductive first radiation unit(11) is formed on one side of a dielectric substrate(10). A conductive ground unit(14) is formed on the other side of the dielectric substrate(10). A second radiation unit(13a) is formed on the other side of the dielectric substrate(10) in a state of being separated from the ground unit(14). A conductive feeding unit(12) is formed on the one side of the dielectric substrate(10) to be connected to the first radiation unit.
