Abstract
Conference Title: 2015 IEEE 12th Malaysia International Conference on Communications (MICC) Conference Start Date: 2015, Nov. 23 Conference End Date: 2015, Nov. 25 Conference Location: Kuching, Malaysia A reconfigurable reflectarray single element and 2×2 sub-array with a single varactor embedded inter-patch are presented. A phase diagram of both configurations and the relation to a radiation pattern is analyzed. Simulated radiation patterns from three designs namely CCSR, CRP and CRG with single element phase characteristics as a reference are reported to demonstrate reconfigurability of elements for beam scanning at Ku-band. The quasi pattern and value of single and 2×2 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 9×3 array by three different elements with 35° scanning angle at Ku-band is compared and has confirmed the important of single and sub-array characteristics in array realization.
