Abstract

Methods of reducing both electric and magnetic field coupling for enhancing the isolation in broadband MIMO antenna system is presented. The proposed MIMO antenna consists of two coplanar waveguide (CPW) fed self-complementary antennas (SCAs) and a U-shaped slot is etched on the ground plane. The protruding structure from the ground plane behaves as both the part of the SCA and an isolator when two SCA protruding structures are connected to each other. Furthermore, the U-shaped slot is introduced for isolation enhancement. The proposed MIMO antenna covers the impedance bandwidth of 4-8 GHz (|S11| ≤ -10 dB) and reaches the good isolation (|S21| ≤ -18 dB) in the band of interest to radar systems.
