The microstrip antenna system uses a special wedge shaped feed connected from the antenna radiation element to the center pin of the coaxial to microstrip adapter to obtain wide bandwidth operation. The special wedge feed connects the center pin to an indefmite series of feedpoints along the length of radiating element. The angle of the taper of the wedge feed along with the distance between the bottom of the wedge and the ground plane provides impedance matching for the antenna.
