Planar monopole antennas for 2.4/5.2 GHz dual-band application

In this paper, we demonstrate two new designs of planar monopole antennas with a shorted parasitic inverted-L wire for achieving dual-band operations: one is a rotated-F planar monopole driven patch coupled with a shorted inverted-L wire and the other is a T-shaped planar monopole driven patch coupled with a shorted inverted-L wire. The proposed antennas can be easily fed by a 50 /spl Omega/ microstrip line printed on the same substrate. Details of the antenna designs and experimental results are presented and discussed.
