Abstract
This invention is to provide a planar monopole antenna operable at two different frequency ranges comprising a patch line printed on a top of a dielectric substrate and having one end formed as a signal feed point; a ground metal plate printed on a bottom of the dielectric substrate; a first radiating element extended from the other end of the patch line beyond the ground metal plate and being perpendicular to the patch line and then further extended a predetermined distance in a direction parallel to the patch line toward and spaced apart from the ground metal plate; and a second radiating element operated at a high frequency projected from a side of the patch line beyond the ground metal plate and spaced apart from the first radiating element operated at a low frequency.
