Abstract
A multi-patch antenna that can transmit radio signals with two frequencies includes a PCB and two stacked-patches. The PCB includes a substrate, a metal layer formed on an upper side of the substrate, and a microstrip line formed on a lower side of the substrate for transmitting radio signals to two slots. The radio signals resonate within the two slots and the stacked-patches, and are then emitted from the stacked-patches in a direction normal to the stacked-patches.
