Abstract

A miniaturization ultra-wideband (UWB) multiple-input-multiple-output (MIMO) antenna with triple-notched band function is presented in the paper. There are two similar monopole radiators in the UWBMIMO system. Based on half-cutting method, the system only occupies 21×27 mm2. Three inverted L-shaped slots are inserted to get three rejected bands for suppressing interference from 3.5 GHz WiMAX, 5.5 GHz WLAN, and 8.1 GHz X-band. With a T-shaped stub extruding from the ground plane, both impedance bandwidth and port isolation are effectively improved. The proposed antenna covers operating frequency band of 3.1-11 GHz except three notched bands, and has a low port isolation of better than -20 dB. Moreover, good radiation patterns, stable gain and low envelope correlation coefficient (ECC) also ensure that the designed antenna is helpful in UWB systems.
