A miniature antenna for various wireless communication applications in the ISM band around 2.45 GHz is provided. The miniature antenna mainly contains a bended planar notch antenna with a metallic stub as a capacitive load. A microstrip feed line is also appropriately bended so as to achieve a significant reduction of the antenna's dimension. The miniature antenna could be implemented using simple manufacturing processes on a common circuit board without mechanical work or advanced processes such as low temperature co-fired ceramics. The antenna has a comparable performance to those antennas having much larger dimensions.
