Low Loss MEMS-Reconfigurable 1-Bit Reflectarray Cell With Dual-Linear Polarization

We present a X-band 1-bit reconfigurable reflectarray (RRA) cell capable of independent reflection phase control of each linear component of a dual-polarized wave. It presents the lowest loss ever reported in an operational RRA cell at microwave frequencies, thanks to particular design considerations and implementation in a monolithic micro-electromechanical systems (MEMS) process. The average reflection loss, including oblique incidence up to theta = 40 degrees, is below 0.6 dB at the operating frequency. Low phase error and loss are preserved in a 12.5% bandwidth. Measurements demonstrate the viability of the concept as well as very good agreement between simulated and measured results.
