Abstract

A composite right/left-handed (CRLH) half mode substrate integrated waveguide (HMSIW) based leaky wave antenna (LWA) is designed and analyzed in this paper. Equivalent circuit of the unit cell is extracted, and the CRLH performance is clarified. Two HMSIW structures are placed back-to-back to obtain low cross-polarization performance, which is further validated by differential excitation principle. The presented LWA is demonstrated to be a balanced structure with a beam scanning range from -60° to +31°. Besides, less than 1.7 dBi gain variation in the working band (46% centered at 13 GHz) is obtained. Simulated and measured results agree well as experiment shows.
