Abstract:A compact CPW-fed ultra-wideband (UWB) multiple-input-multiple-output (MIMO) antenna with quad-band-notched characteristic is proposed in this work.The antenna elements are placed orthogonally, the introduction of defected ground structure (DGS) and double Y-shaped stub makes the isolation between different antenna ports better than 20 dB, and the cutting of the excess dielectric substrate part reduces the antenna area by about 30.75%. Complementary splitring resonators and slots on the ground and the radiatio… Show more
