• To develop the effective feeding structure for the leaky wave antenna using the composite right/left-handed transmission line with monopolar radiation, a broadband center-feed structure composed of a triangular element is proposed in this paper. The dispersion characteristics and flat Bloch impedance are obtained by complex S-parameters of 2 ports on the structure. The CRLH leaky wave antenna is fabricated, and bandwidth of 60% is achieved while its radiation characteristics are similar to monopolar radiation.
