Abstract :
The leakage characteristics of a new grating leaky wave antenna based on left-handed material are carefully analyzed using a method which combines the rigors mode matching procedure with multimode network method. The variations of the leakage constant with structure parameters are given in this paper, to show the special properties of this kind of antenna. The numerical results indicated that the new leaky wave antenna is of much larger leakage constant than that for the conventional one. The reason for this phenomenon is discussed
