Compact Broadband Wilkinson Balun Using Metamaterial Transmission Lines

Recently, various structures such as zeroth order antennas, dual band branch line couplers, compact ring hybrids, broadband baluns, and so on, have been introduced by using metamaterial transmission lines (MTM TLs) of the composite right/left handed (CRLH) or the LC loaded (LCL) lines [1-2]. In general, most of passive circuits in RF/microwave systems are… CONTINUE READING
