A cross-mesh array antenna

A grid array antenna, which is backed by a conducting plane, is a low-profile flat antenna consisting of numerous radiation and transmission line elements. This paper presents a cross-mesh (CM) array antenna, which is regarded as an extension of the grid array antenna. The CM array antenna is decomposed into two grid arrays (x- and y-directed grid arrays). It is emphasized that the CM array antenna has four feed points, unlike the grid antenna: a, b, c, and d, where a and c belong to the x-directed grid array and b and d belong to the y-directed grid array. The purpose of this paper is to reveal the radiation characteristics of the CM array antenna
