A shorted-patch antenna with a U-shaped coupling slot for broadband operation is presented.The U-shaped coupling slot etched on the ground plane is located in close proximity to the shorting wall to obtain a good impedance matching. Using an L-shaped shorting wall with a height of about 6% wavelength at the center operating frequency and a U-shaped coupling slot, the proposed microstrip patch antenna has a compact size and broadband operation. The proposed antenna yields a wide bandwidth of about 33.6% and a peak gain of 4.2 dBi.
