DOI:10.1109/LAWP.2014.2372316.png)
摘要
En 中文
In this letter, new phase-shifter cells for reflectarray applications using the cut-ring patch coupled to the delay line through an annular slot are presented. The new configuration allows the phase shift to be obtained by adjusting the length of a single or two different delay lines. Various prototypes of the elements have been fabricated and measured in X-band using the waveguide simulator technique. A good agreement between the measurement and simulation for both reflection phase and magnitude is achieved. Experimental results indicate good characteristics of the reflectarray element with a wide range of reflection phase and good linearity of the phase curve.
