The various properties such as the electric current distribution, resonant frequency and radiation patterns of open-ended meander slot antenna placed on a small ground plane, are investigated to give the help in performing antenna design. Based upon these characteristics, the designed antenna which is only 22mm(0.06λg) in height and 31mm(0.09λg) in width can operate at the 433 MHz with the measured radiation efficiency of 8% and end-fire radiation pattern. These properties make the antenna suitable for the handheld device such as the wireless remote controller.
