Described is a novel structure of a various-size slits and slots arrayed antenna using a large offset dual-point feed line, which has similar radiation pattern properties. In this case, the large-offset dual point feed line leads to good impedance matching in a wide frequency band. Inserted variable size slits and slots arrayed on the radiator act as a multi-band resonant element of the antenna. Experimental results of a constructed prototype covering the usable bandwidth of the DCS, PCS, IMT 2000 operations are presented.
