Claim Text:
1. A loop antenna comprising an antenna element having a shape that traces a closed curve, the antenna element including (i) a first projection section which projects from one of two end sections of the antenna element toward an inside of the closed curve and (ii) a second projection section which projects from the other of the two end sections of the antenna element toward the inside of the closed curve, each of the first projection section and the second projection section including a feed point, wherein: where a direction in which both ends of the antenna element are located as viewed from a center of the closed curve is a six o'clock direction, the first projection section is constituted by a first linear section and a second linear section, the first linear section extending in a twelve o'clock direction from a starting end section, which is one of the two end sections of the antenna element which one is a starting point of a line obtained by tracing the closed curve clockwise, the second linear section extending in a three o'clock direction from an end section, located in the twelve o'clock direction, of the first linear section; the second projection section is constituted by a third linear section and a fourth linear section, the third linear section extending in the twelve o'clock direction from a terminus end section, which is one of the two end sections of the antenna element which one is an ending point of the line obtained by tracing the closed curve clockwise, the fourth linear section extending in a nine o'clock direction from an end section, located in the twelve o'clock direction, of the third linear section; and the second linear section of the first projection section and the fourth linear section of the second projection section each including the feed point.
