Patch antenna and manufacturing method of patch antenna

摘要

Problem to be solved: to limit the limitation of the high performance directivity design by limiting the adjustment ratio of the distribution power of the power supply distribution circuit, and to mount all the parts including a plurality of patch antenna elements and a power supply distribution circuit on the same plane of the substrate.Solution: in the series feed patch array antenna 10 of a linear 8-element array arrangement, by radiating power control element 22 disposed near each patch antenna element By controlling the radiation power of the patch antenna element 14, the limitation of the high performance array antenna directivity design by the restriction of the adjustment ratio of the distribution power of the power supply voltage distribution control circuit 16 can be relaxed.Further, the plurality of patch antenna elements 14, the power supply distribution control circuit 16, and the radiation power control elements 22 disposed in the vicinity of the patch antenna elements 14 can be mounted on the same plane of the planar substrate 12.Diagram
