Abstract
A novel broadband patch antenna with electric- and magnetic-coupled elements and its application in multiple-input-multiple-output (MIMO) system is proposed in this communication. Unlike the conventional gap-coupled patch antennas, the electric and magnetic coupling between adjacent patches is considered and studied. Also, for improved understanding of the broadband nature of the proposed configuration, the phase relationships between patch elements are studied. Two- and three-patch prototypes are designed for validation of the concept, and the three-patch antenna is fabricated and measured showing a good agreement between the measured and simulated results. Considerable selectivity is observed in the results of the three-patch antenna because of the radiation nulls introduced by the electric and magnetic coupling. Apart from the broadband operation, the proposed antenna elements show promise for application in high-isolation MIMO systems due to their inherent band-reject characteristic when they are closely placed. For validation in this application, a four-element MIMO antenna is designed, fabricated, and measured. The measured results agree well with the simulated ones.
