DUAL BAND ANTENNA SATISFYING WLAN AND LOW UWB FREQUENCY BAND AT THE SAME TIME

摘要

PURPOSE: A dual band antenna for WLAN and low UWB is provided to minimize feeding loss by forming a ground surface and a CPW(Coplanar Waveguide) feeder on the same surface.;CONSTITUTION: A radiation patch(120) is formed on a dielectric substrate(110) with a symmetrical structure. A stub(130) for generating a WLAN(Wireless Local Area Network) frequency is formed between the radiation patches with a T-shape. The upper center of the stub for generating the WLAN frequency is opened. A stub(140) for the junction connects the radiation patch. A CPW feeder(150) is connected to the lower side of the stub for the junction. A ground surface(160) is positioned on both sides of the CPW feeder.;COPYRIGHT KIPO 2010
