MUTUAL COUPLING REDUCTION BETWEEN CLOSELY PLACED MICROSTRIP PATCH ANTENNA USING MEANDER LINE RESONATOR

Abstract:
An approach of reducing Mutual Coupling between two patch antennas is proposed in this paper. Here, a meander line resonator is placed in between the radiating elements. By inserting the meander line resonator between the patch antennas with the edge-to-edge distance less than λ/18, about 8 dB reduction of Mutual Coupling throughout the 10-dB bandwidth has been achieved without degrading the radiation pattern.The circuit model of the proposed configuration is carried out in this paper and envelope correlation coefficient is also computed. The proposed structure has been fabricated and measured.
