Abstract
A microstrip patch antenna including a ground plane base, an L-shaped feed structure and a laminate structure is disclosed herein. A matching network is formed by a clearance member of the laminate structure around a pin and a stub of the L-shaped feed structure on the bottom surface in which the clearance member around the pin effectively decreases shunt inductance and reduces a series capacitance at a feed point to enable a 50 ohm wideband operation.
