Title:
REFLECT-ARRAY ANTENNA
Document Type and Number:
WIPO Patent Application WO/2018/020550
Kind Code:
A1
Abstract:
It is arranged that the board thickness t of a dielectric board (1) and the element interval d of a plurality of resonant elements (2) be determined according to a design value Ldes for an attenuation amount L by which a higher order mode occurring in the resonant elements (2) upon incidence of an electromagnetic wave on the dielectric board (1) attenuates during propagation through the dielectric board (1). This makes it possible to suppress the occurrence of a basic mode having a different propagation constant from the propagation constant the basic mode of the incident electromagnetic wave has. As a result, the frequency band of a reflect-array antenna can be widened as compared to a case where only the shapes of the resonant elements (2) are devised.
