Corporate-fed 2×2 planar microstrip patch sub-array for the35 GHz band

摘要

A classical configuration of a planar array of microstrip rectangular patches, fed by a corporate-feed arrangement, is widely used for many applications. There are several reports devoted to the design of such antennas. However, they are based on semi-empirical approaches, especially at mm-wave frequencies. A good choice of an array-feeding-network layout is a cornerstone problem for the antenna's design. The purpose of this report is to give a description of a 2×2 element planar microstrip-patch sub-array, which can be used as a basis configuration for design of large, high-gain arrays, for the 35 GHz band
