Mutual coupling reduction in multilayer patch antennas via meander line parasites

A method to reduce the mutual coupling in wide-band multilayer patch array operating in C band is presented. The proposed device use conveniently sized meander line parasites printed on the same substrate of the upper patch. Measurements on a $2 \times 2$2×2 prototype shows a measured bandwidth of a...

description A method to reduce the mutual coupling in wide-band multilayer patch array operating in C band is presented. The proposed device use conveniently sized meander line parasites printed on the same substrate of the upper patch. Measurements on a $2 \times 2$2×2 prototype shows a measured bandwidth of about 19.6% centred at 5.1 GHz, therefore adequate to cover the whole WLAN frequency range. The meander lines allow to reduce the patch mutual coupling by about 2.4 dB.
