An enhanced decoupling technique between two patch antennas is proposed in this letter based on the common-mode (CM) and differential mode (DM) theory. Two symmetrical antennas theoretically proved that if the impedances of CM and DM are the same, the mutual coupling effect between the separate antennas can be eliminated. Two parasitic patches are located above two identical patches spacing with 0...Show More
An enhanced isolation technique between two low-profile patch antennas is proposed. Two identical antennas are configured with two printed circuit boards (PCBs) spaced at 0.206λ0, where λ0 is the free-space wavelength at 3.5 GHz. Every antenna is a rectangular patch with four slots and two vias, vertically fed with a coaxial probe. A decoupling strip embedded between two antennas and a slot on the...Show More
