Paper Abstract

We present a flexible active 2-bit 2-element phased-array antenna (PAA) fully fabricated using ink-jet printing technology. High speed carbon nanotube (CNT) based field effect transistors (FETs) function as switch in the true-time delay line of the PAA. The 2-bit 2-element active PAA is printed out at room temperature on 100μm thick Kapton substrate. The FET switch works well for 5GHz RF signals. An ON-OFF ratio of over 100 is obtained at a low Vds bias of 1.8V. The measured azimuth beamsteering angles of PAA agree well with simulation values.
