Application8 Wideband Leaky Wave Antenna System – Kitazawa Lab., Department of Electrial and Electronic Engineering, Ritsumeikan University –

The wideband leaky wave antenna, which is intended for the next-generation use, was analyzed.
As shown in Fig. 1, the antenna consists of two microstrip lines. The composite right/left-handed transmission line (CRLH-TL) technique was used.
Figures 4, 5, and 6 show high gain in the wide bandwidth.
