Reflectarray with EBG elements for improved radiation characteristics

A reflectarray composed of elements with electromagnetic bandgap (EBG) characteristics to improve radiation performances is proposed. The EBG elements are composed of patches and multiple via-holes to provide required reflection phase and bandgap characteristics at target frequency of 10 GHz. Compar...

Zusammenfassung:A reflectarray composed of elements with electromagnetic bandgap (EBG) characteristics to improve radiation performances is proposed. The EBG elements are composed of patches and multiple via-holes to provide required reflection phase and bandgap characteristics at target frequency of 10 GHz. Compared with a normal patch reflectarray without EBG elements, the gain is improved by 1.4 dB; and the SLLs are suppressed by 1.5 dB (E-plane) and 5.3 dB (H-plane), respectively.
