Abstract :
A novel unit cell of a composite right/left-handed transmission line has been proposed for application in leaky-wave antennas. It is shown that by the application of an open stub one can freely adjust the radiation frequency range in the right-hand region, and therefore, scanning of the main beam in the desired frequency range can be obtained. The results of theoretical analysis of the unit cell have been shown and confirmed by electromagnetic calculation of the proposed structure.
