In this paper, a printed inverted-F antenna for dual-band dual-sense circular polarization is proposed. The bandwidth of 10 dB-return loss with a 3 dB-axial ratio is 5.5% for 2.5GHz band, and the one for 3.5GHz band is 10.0%. Antenna performance and operation principles of the proposed antenna are analyzed and discussed in detail. Antenna dimension is 0.39λfL×0.18λfL(fL is the center frequency for the lower frequency band). The size of the proposed antenna is very compact.
