摘要：
A compact coplanar waveguide (CPW)-fed multiple-input-multiple-output (MIMO) band-notched antenna with a small size of 20x36x0.8 mm(3) for ultrawideband (UWB) system is proposed in this paper. The two rectangular monopole (RM) elements fed by CPW are printed on the FR4 substrate. To improve impedance bandwidth and the isolation, a T-shaped stub structure is positioned in the middle of two RM elements. The band-notched characteristic is achieved by etching a U-shaped loop resonator slot on each RM element. The S-11 reflection coefficients, S-12 coupling isolation, radiation pattern, peak gain and radiation efficiency of the MIMO antenna are measured. The MIMO performance of the proposed MIMO antenna is analyzed and evaluated by the envelope correlation coefficient (ECC) and total active reflection coefficient (TARC).
