Abstract

In this paper, design, fabrication and measurement results of the 1st MEMS based, passive subarray are discussed. Distributed MEMS transmission lines (DMTL) by Barker and Rebeiz are used, which are the lowest loss analog time delay units (TDUs) currently available. It outperforms contemporary MMIC, ferroelectric and photonic true time delay (TTD) units in terms of loss and outperforms digital beam forming (DBF) technology in terms of cost and feasibility. Also, in contrast to switched beamforming networks (BFN) based on SPNT switches and constrained lenses, such as the bootlace, Rotman and Archer lens, the noise figure of the passive line array scales with the amount of antenna elements and the transmit power is distributed and not limited by the SPNT, making it the subarray of choice for future integration in an ESA.
