Abstract

In this paper, a 4×4 MIMO-UWB antenna rejected WLAN band based on Electromagnetic Bandgap (EBG) is presented. The MIMO antenna is printed on a FR4_epoxy substrate with the dielectric constant of 4.4 and a thickness of 1.6 mm. A mushroom-like EBG is used to reject the WLAN frequency at 5.5 GHz. In order to reduce the mutual coupling of the antenna, a stub structure acting as multi-mode microstrip resonator is inserted to suppress the effect of surface current to the elements of the proposed antenna. The results demonstrate that the mutual coupling is reduced and the values of all isolation coefficients are below -15 dB. The antenna has a compact size of 60mm×60 mm.
