Abstract :
A kind of circularly-polarised radial line slot antenna for high-power microwave application is proposed by contriving a kind of radial line slow-wave structure, an improved circularly-polarised radiator unit and a reflection cancelling slot. An antenna prototype with a length of 12 cm and an aperture diameter of 54 cm is designed, which has a gain of 29.0 dBi and an axial ratio of 1.12 at 9.42 GHz. The high-power experiment proves that this antenna has a power-handling capacity of more than 600 MW.
