A new type of loop antenna with core of fan-shaped plasma is designed. When the plasma frequency is about 4 times of the antenna frequency, the radiated power of loop antenna is enhanced greatly. Numerical analysis shows it is the resonance of electric field between plasma and dielectric of positive permittivity, which enhances the radiated power. Furthermore, the effects of parameters of antenna core on radiation characteristics are studied.
