Abstract
A planar L-shaped antenna. The antenna is operable at two different frequency ranges and includes a patch line printed on top of a dielectric substrate and has one end formed as a signal feed point. A ground metal plate is printed on a bottom of the dielectric substrate. First and second radiating elements extend oppositely from another end of the patch line. The first and second radiating elements are perpendicular to the patch line and disposed above and beyond the ground metal plate for receiving signals having different frequencies respectively.
