1. An antenna system, comprising:
a substrate having a top side and a bottom side;
a single straight microstrip line on the top side of the substrate, an input end of the single straight microstrip line being adjacent and vertical to a first edge of the substrate, and an output end of the single straight microstrip line being open;
a microstrip power divider (PD) on the top side of the substrate, an input end of the microstrip PD being adjacent and vertical to a second edge of the substrate, eight output ends of the microstrip PD being open, and the first edge being parallel to the second edge; and
a ground plane on the bottom side, three concentric square slots being etched on the ground plane.
