Phase-Shifting Cell Loaded with Variable Capacitances for Dual Linearly Polarized Reflectarrays
نویسندگان
چکیده
A new dual linearly polarized phase-shifting cell for reflectarray applications is presented. It consists of two orthogonal sets of parallel rectangular slots etched in a ground plane. Each set may be loaded with a combination of variable and fixed capacitances to provide a reconfigurable 2-bit phase-shifter for both polarizations. A passive version of the proposed cell has been fabricated and characterized in Cband with four fixed states. For each polarization only two variable capacitances are needed in order to control the phase of the reflected wave.

Dual-annular Slot Phase-shifting Cell Loaded with Mems Switches for Reconfigurable Reflectarrays
Reconfigurable reflectarrays require low-loss and lowdispersion active cells in order to achieve efficient beam scanning or beam shaping on a large bandwidth. The low-loss constraint is the more stringent as the introduction of tunable components (such as MEMS) in resonant phase-shifting cells may dramatically decrease their quality factor. In this paper, a comprehensive review of recent develo...
متن کاملSingle-Layer Dual-Band Dual-Linear-Polarization Reflectarray Antenna with Different Beams for Each Band
A novel single-layer unit cell structure is proposed to design a dual-band dual-linearpolarization reflectarray antenna with different beams for X and Ku bands. The unit cell structure is composed of a circular ring and two cross bow-tie structures combined by a circular patch. Five tunable geometric parameters can be optimized to achieve the required phase distributions of the reflectarray ant...
متن کاملTriple-slot phase-shifting cell loaded with one variable capacitance for reflectarray applications
Introduction: Active reflectarrays are promising solutions for reconfigurable radiating apertures at reasonable cost [1]. One of the main challenges is to design phase-shifting cells whose phase can be controlled dynamically over a 360° phase range with smooth frequency variations, low losses and reduced number of active elements. MEMS [2] or diodes [3] are usually used to dynamically control t...
متن کاملReflectarray Antennas
Printed reflectarrays combine certain advantages of reflector antennas and phased arrays. One major hurdle in the designing of reflectarrays is the compensation of phase difference between various elements. This paper presents reviews of various techniques for phase compensation, like using variable sizes of the patch, adding stubs of variable lengths and use of variable size slots on the groun...
متن کاملInvestigation of molecular motion of Cl-adamantane in the nanoprous zeolite by 13C NMR dipolar dephasing and variable contact time measurements
Dipolar-dephasing method provides some information about the strength of dipolar coupling in solids. Dipolar dephasing technique measures the time for a polarized carbon nucleus to lose its magnetization once the proton locking field is terminated. The dynamics of guest molecules adsorbed within the cavities and channels of nonporouszeolite strongly depend on the structure and chemical composit...
