Abstract :
An 8-element planar composite right/left-handed (CRLH) leaky wave antenna (LWA) array fed by an 8 times 8 Butler matrix feeding network is designed and its 2-D beam steering characteristics are demonstrated numerically. The 2-D beam steering is expected in one plane by changing frequency and also in the other orthogonal plane by switching the input port of the BM. The CRLH LWA element and the BM are designed in the microstrip line configuration and overall radiation characteristics of the antenna array are predicted numerically.
