Abstract :
Frequency scanning antenna array based on composite right/left handed (CRLH) phased-array feed network is presented. The proposed array design method enables continuous beam scanning obtained through the feeding network design, which is different from the widely researched CRLH based leaky-wave antennas. It allows an added degree of freedom in designing frequency scanning antennas by taking the advantages of controlling the aperture field distribution and decoupling the element patterns from the array factor (AF) patters.
