Patch antennas are known for narrow bandwidth, depending on substrate height, but which can be improved by multilayer construction or by integration of extra matching circuits. The contribution presents a new approach to bandwidth improvement of patch array antennas, where conventional single layer patch elements are combined through a modified feed network. The network includes matching elements for each patch radiator without additional space requirement and without degradation of the fundamental feed network purpose. A 24 GHz 2 x 4 element array is shown to provide an improvement of bandwidth from 6% of the patch element alone to 13% of the array.
