N-port feeding system having a structure in which patterns are divided with in parallel and feeding element included in the same

A feeding element comprising:

• a first substrate;
• first patterns disposed on the first substrate;
• and
• second patterns disposed on the first substrate, and connected electrically in parallel to the first patterns,
• wherein the first patterns are electrically connected each other by third patterns on a second substrate spaced from the first substrate, and the second patterns are electrically connected each other by fourth patterns on the second substrate.

A feeding system comprising:

• a first substrate;
• first patterns disposed on the first substrate;
• second patterns disposed on the first substrate, and connected electrically in parallel to the first patterns;
• a division system disposed on the first substrate, and configured to supply a power to the first patterns and the second patterns;
• a second substrate spaced from the first substrate;
• at least one third pattern disposed on the second substrate, and configured to correspond to the first patterns;
• and
• one or more fourth pattern disposed on the second substrate, and configured to correspond to the second patterns,
• wherein the first patterns and the second patterns are electrically connected to radiators through cables, respective cables have different lengths, and electrical lengths from outmost pattern of the first patterns to corresponding radiators and electrical lengths from outmost pattern of the second patterns to corresponding radiators have the same length.
