A novel dielectric gate leaky wave antenna based on left hand medium is proposed, and the radiation characteristics of the left hand dielectric gate antenna are carefully and strictly analyzed by the combination of multimode network and strict modulus matching. The relationship between the wave coefficients and the parameters of the antenna structure shows the unique properties of the left-handed antenna, and the numerical results show that the new type of leaky-wave antenna has stronger radiation capability than the traditional dielectric gate antenna.
