In this letter, a new compact antenna design with triple-sense circular polarization (CP) is presented for ultrawideband (UWB) communication applications. The UWB property is obtained by utilizing a compact complementary planar monopole. In order to achieve multiband CP waves on base of UWB operation, the measurement has been taken such as etching a T-shaped slit in the antenna ground and adding a rectangular parasitic stub to the antenna radiator. The antenna has been fabricated and measured. Good agreement is achieved between the simulation and measurement, which shows that the presented antenna covers the UWB operation from 3.1GHz to 11.8GHz with good CP waves at Worldwide Interoperability for Microwave Access (WiMAX) (3.63-3.77 GHz bands) for left hand CP (LHCP), the wireless local area network band (WLAN) (4.95- 5.18 GHz bands) for right hand CP (RHCP), and X band (9.55- 9.97 GHz bands) for left hand CP (LHCP).
