## Abstract This article demonstrates, for the first time, a dual‐band branch line coupler based on composite right‐/left‐handed transmission lines with series capacitors only.The complete elimination of shunt inductors provides a potential for the proposed CRLH transmission lines to be applicable
## Abstract A novel composite right/left‐handed transmission line unit is proposed. Using the structure, a new power divider is developed. By adjusting the parameters of the capacitors and the inductors, the simulation results show that the power divider has perfectly symmetric power division at 1.
## Abstract A dual‐band RF switch that utilizes composite right/left handed (CRLH) transmissions‐lines(TLs) and PIN diodes is proposed. The design method of RF switch is based on the phase characteristic of the CRLH‐TL, which can be adjusted arbitrary, and employed conventional type‐II; filter stru
