Abstract

A compact dual band-notched ultra-wideband (UWB) multiple-input multiple-output (MIMO) antenna with uniform rejection performance is designed on an FR4 substrate (35×23×1.6 mm³). Compared with the existing UWB MIMO antennas, a second-order notched band with uniform performance for 5.15-5.825 GHz is achieved, which results from the interplay between a 1/3λ open-end slot and a 1/2λ parasitic strip. A 1/4λ open-end slot is also applied to the 3.3-3.7 GHz reject band. The two slots are connected at their open ends, that can help to get the uniform reject performance for 5.15-5.825 GHz and make the high cutoff frequency of the impedance matching band go toward the higher frequencies. Excluding the two rejected bands, a band with |S₁₁|≤-10 dB, |S₂₁|≤-17 dB and frequency ranged from 3.1 to 10.9 GHz is achieved, and results show that a uniform performance for 5.15-5.825 GHz is obtained.
