Abstract
In this paper we proposed a novel dual-band compact folded patch antenna with the same linear polarizations and high isolation characteristic between the two frequency range. The antenna is loaded with a high permittivity dielectric material in order to reduce the antenna size and open circuit stubs are used in order to broaden the bandwidth. The fractional bandwidths of the optimized antenna with demensions 4 mm${\times}$3 mm${\times}$5 mm are 3.0 % at 5.6 GHz band and 2.8 % at 5.8 GHz band, respectively. The isolation characteristic between the two ports is less than -26 dB within the operating frequency range.
