UWB(ULTRA WIDEBAND) ANTENNA WITH A MULTIPLE BAND REJECTION FUNCTION CAPABLE OF EFFICIENTLY CONTROLLING THE PROPERTY OF EACH BAND USING THE REJECTION DEVICE FOR DIFFERENT BANDS AND A DESIGNING METHOD THEREOF
PURPOSE: An UWB(Ultra Wideband) antenna with a multiple band rejection function is provided to prevent performance degradation due to coupling between devices by minimizing coupling between band rejection devices.;CONSTITUTION: An antenna(100) comprises a substrate(110), an emitting unit(120), and a feeding unit(130). The antenna has a bilateral symmetric shape along a central line excluding a meander line. The substrate is composed of the dielectric substrate with a constant dielectric permittivity. The emitting unit is formed in one side of the substrate to receive and transmit an ultra wideband electric wave. The emitting unit is a square shaped patch with a matching step in a lower unit. The power feeding unit is formed in the lower unit of the emitting unit. The power feeding unit is composed of a feeding line(131) which supplies an electric signal and a first ground(132) and a second ground(133) which are formed in the left side of the feeding line.;COPYRIGHT KIPO 2012
