SIMPLE WAVEGUIDE FEEDING NETWORK AND A FLAT WAVEGUIDE ANTENNA THEREOF

摘要

PURPOSE: A waveguide feeding network is provided to be very simply and easily designed by using only the structure of the widely used conventional waveguide and a flat waveguide antenna is provided to enable deformation to the various kinds of a waveguide feeding network and to decrease the possibility of generating loss, by reducing the number of vertically connected waveguide feeding networks.;CONSTITUTION: A waveguide feeding network includes: a first port(10); second ports(20) arranged in one direction; an E-Plane feeding network unit consisting of N sets(N is an integer), wherein the first set is an E-Plane T divider the common conduit of which is connected to the first port, the respective other sets consist of E-Plane T dividers which is formed of two secondary conduits connected to the common conduit, and E-Plane Bends which is connected to the conduit, and the common conduits of E-Plane Bends of Nth set and the first conduit of E-Plane Bend are connected to the secondary conduits of E-Plane T divider of n-1st set or the second conduits of E-Plane Bend, and every Nth set is made of only E-Plan Bend; an H-Plane feeding network unit which forms a determined angle with the first conduit, consists of H-Plane Bend connected with the second conduit, is connected with the second conduits of E-Plane Bend of the Nth set of E-Plane overall feeding network part, wherein the each of the second conduit directions of H-Plane Bend are the same with each other, and constitutes of N+1th set; and an E-Plan rear feeding network unit which consists of E-Plane T dividers and E-Plane Bends and constitutes of N+2th set, wherein the common conduits of E-Plane T divider and the first conduit of E-Plan Bend are connected with each other, respectively.;COPYRIGHT KIPO 2013
