英文摘要	The composite right/left-handed (CRLH) transmission line (TL) based leaky-wave antennas (LWAs) are usually constrained by wide frequency scanning bandwidths to achieve certain beam scanning range. This is mainly due to that the fast wave region of the CRLH cell dispersion is insensitive to the frequency. In this work, we propose a substrate integrated waveguide (SIW) CRLH cell structure with dispersion sensitivity improved. This advantage makes the structure have a narrower fast wave region and thus have a potential application to the LWA with a large beam scanning range (BSR)/bandwidth ratio. The simulated and experimental results of this CRLH unit cell are both given to confirm the validity of the dispersion sensitivity promotion.
