Abstract

The design of reconfigurable reflectarray with a single varactor to provide capacitance effect embedded inter-patch are presented. The essence of this concept lies in the behavior of the capacitance variation contributes to phase changes of element. Simulated radiation patterns with single element phase characteristics as a reference are reported to demonstrate reconfigurability of elements for beam scanning at Ku-band. The consistency in pattern and value of single and 2x2 sub-array will provide guideline and indicator on how to get promising beam scanning result for full reflectarray fabrication and measurement. The radiation pattern of linear array by three different elements with 35° scanning angle at Ku-band is analyzed and has confirmed the important of single and sub-array characteristics in array realization.
