Title:
溝寸法可変な反射板
Document Type and Number:
Japanese Patent JP4249189
Kind Code:
B2
Abstract:
The present invention relates to a reflecting board for a microstrip reflectarray antenna and, more particularly, to a reflecting board with variable slot size that can improve the design flexibilities of the reflecting board and reduce the sensitivity to the manufacturing tolerances of the microstrip reflectarray antenna. The reflecting board comprises a bottom substrate having a first lower surface, and a top substrate. Plural first microstrip antenna patches, and plural second microstrip antenna patches with rectangular slots are disposed on the upper surface and the second lower surface of the top substrate, respectively. The area of the second microstrip antenna patches is larger than that of the first microstrip antenna patches. Besides, the ratio of the maximum border-length of the rectangular slot to the maximum border-length of the corresponding second microstrip antenna patch is identical for each second microstrip antenna on the second lower surface of the top substrate.
