1. An antenna element comprising:
a multi-layer printed circuit board (PCB), the PCB including a top metal layer, a second metal layer, a third metal layer, and a bottom metal layer, the PCB including dielectric layers positioned between each of the metal layers, a thickness of the PCB being defined by a total thickness of the layers, the top metal layer, the second metal layer, and the third metal layer all of different lengths, the second metal layer and the third metal layer including a plurality of slots formed therein, each of the plurality of slots having a size and a position tuned to a central frequency and frequency bandwidth;
wherein each of the top metal layer, the second metal layer, the third metal layer, and the bottom metal layer have a shape of rectangular arms, a length of the top metal layer being shorter than a length of the second metal layer, the length of the second metal layer being shorter than a length of the third metal layer, and the length of the third metal layer being shorter than a length of the bottom metal layer.
