Abstract--An artificial transmission line unit cell is presented
based on the so-called composite right/left handed transmission
line. It is implemented on a microelectromechanical system process
on glass, and is suitable for applications such as reconfigurable
leaky-wave antennas and series feed networks. The device presents
state-of-the-art performance in terms of differential phase shift
over losses (38 dB at 14 GHz) and quasi-zero drive power con-
sumption. It is monolithic and has a total footprint of 4 mm2.
Index Terms--Artificial transmission line, composite right/left-
handed (CRLH), metamaterial, microelectromechanical system
(MEMS), reconfigurable.
I. INTRODUCTION
Awide range of microwave devices with enhanced per-
formances have been developed using the particular
dispersion of the composite right/left handed transmission line
(CRLH-TL) structure [1], [2]. However, although high fre-
