Abstract

A feeding network with composite right/left-handed transmission line (CRLH-TL) for 2-dimension millimeter wave microstrip patch arrays is proposed. Because of the simpler structure and the shorter length of the CRLH-TL feeding network, the antenna array is of higher gain than that with the parallel feed network. Besides, the radiation pattern shift resulting from the traditional parallel-series feeding network is removed since no inserting phases shift are introduced in the patch elements using the feeding structure.
