Isolation Enhancement of a Very Compact UWB-MIMO Slot Antenna With Two Defected Ground Structures Used in Multi band Applications
International Research Journal of Engineering and Technology
unpublished
Preserved Fulltext
A multiple-input multiple-output (MIMO) antenna which has a compact size of 22×26 mm² that operates in ultra wide band range of 3.1-10.6 GHz is presented. The antenna exhibits high isolation to improve the impedance matching characteristics in low frequencies as well as reduces mutual coupling less to than 18db for high frequencies. A T shaped slot is cut from the ground. The performance of this antenna is studied and measured by simulation. The results indicate that the proposed antenna is a good candidate for UWB applications.
