Abstract:
1. 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 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 third pattern connects electrically corresponding first patterns, and the fourth pattern connects electrically corresponding second patterns, the first substrate or the second substrate moves while changing phase of an RF signal provided to a radiator, a part of the first pattern overlaps with a part of the third pattern, and electrical length of overlap area of the first pattern and the third pattern varies while changing the phase.
