Abstract:
     The left hand microstrip transmission line (MTL), and time delay line based on the said MTL are produced from medium covered conductor plate. Capacitance is formed by two frames of plane cross fingers structures produced on conductor layer on up surface of medium plate. Moreover, via hole is prepared on outer cross finger or side strip on each plane cross fingers structure. Conductors on via holes connect capacitances to ground so as to constitute inductance. Ports of inputting and outputting signals of MTL are located at side strips on two ends of cross fingers capacitance. On plane carrier, the left hand MTL realizes series capacity and shunt inductance directly with features of compact structure, easy of manufacture, small size, low loss, and capability of applicable to microstrip IC. The MTL possesses symmetric structure, multiple adjustable parameters so as to suit requirements by different performances and different applications easily.
