Study on dual frequency planar monopole antennas

This paper studies a kind of miniature dual-frequency planar monopole antenna, which designed by using a inverted-F adds inverted-L structure and the balanced loading of inductance in the antenna structure. One of the most advantages of the antenna is small ground plane and wideband characteristics in syntonic frequency in low frequency band. It provides a new technique for the miniaturized design of planar monopole antenna.
