Abstract (en)
[origin: WO2009093779A1] The present invention relates to a feeding network structure for a flat type antenna, which reduces sidelobes by controlling radio wave transmission and reception intensities so that a center of an antenna has radio wave transmission and reception intensities higher than a peripheral portion by configuring a "T" type distributor of a feeding network in an asymmetrical structure having different widths.
