Abstract :
A composite right/left-handed transmission line is used in an array for two-dimensional beam scanning. This type of transmission line, acts as a guided-wave or leaky-wave structure depending on frequency. This dual utility allows for a simple and inexpensive array that can be scanned independently in two planes. The fabricated array demonstrates a scanning range that is as great as -42deg to 21deg in one plane and -21deg to 15deg in the orthogonal plane
