N-PORT FEEDING SYSTEM HAVING A STRUCTURE IN WHICH PATTERNS ARE DIVIDED WITH IN PARALLEL AND FEEDING ELEMENT INCLUDED IN THE SAME

摘要

PURPOSE: An N-port feeding system and a feeding device included in the same are provided to reduce the size of an antenna by feeding electricity by using conductor patterns having a distribution structure. CONSTITUTION: First patterns(214) are arranged on first substrate(210). First coupling prevention elements are arranged between the first patterns in order to prevent coupling of the first patterns. Second patterns(216) are arranged on the first substrate and are connected to the first patterns in a row. Second coupling prevention elements are arranged between the second patterns. A second substrate(212) is separated with the first substrate. A third pattern(228) corresponds with the first patterns. A fourth pattern(230) corresponds with the second patterns. The third pattern electricity connects the first patterns. The fourth pattern electrically connects the second patterns.
