A high scanning rate circular polarization leaky-wave antenna fed by allpass filter is proposed. It characterizes large scanning rate and circularly polarization in the applicable frequency band. Cascaded 90 degree crossed slots and allpass filter are employed to produce circular polarization and beam steering. The group delay of allpass filter can be engineered in order to enhance the scanning rate. Simulated results indicate a scanning range from 35 degree to 65 degree, which scanning rate of 300 degree/GHz, and axial ration is below 3dB in 100MHz.
