Abstract
An antenna for RFID (Radio Frequency Identification) configured to be electrically connected to an IC (Integrated Circuit) chip or capacitor and configured to be affixed to an article. The antenna includes: a planar conductive member having a first side configured to be mounted on the article; and a coil body configured with coil turns and mounted on or at a second side which is opposite to the first side of the conductive member. The number of the coil turns and diameter of the coil body are adjusted such that a characteristic of said coil body has a predetermined value. The conductive member shields the coil body from the article.
