Mutual Coupling Reduction between Patch Antennas Using Meander Line
International Journal of Antennas and Propagation, 2018 Meander lines (MLs) in two configurations are presented to reduce the mutual coupling (MC) between two microstrip patch antenna elements. Inserting a slot in the ground plane between the antenna elements is a simple method to reduce the MC, while adding ...
