ISM band, the present invention is used for a dual-band planar antenna on the station -F for such, in particular ground and the separation of the patch and the ground plane to which two short plates at the edge of the patch is formed on one side of the surface , to form a single slot to cut a portion of the patch , a double band for the ISM band to one antenna may implement the antenna , it is possible to reduce the size of the antenna by using the two short plates , the first band of the resonance frequency and the second resonance frequency can be independently controlled . Also, because it uses a single slot design is simple and easy to manufacture .
