ABSTRACT:
An antenna apparatus for receiving an electric wave, includes an antenna element for receiving an electric wave made from an elastic linear body of a loop shape which can be collapsed into a plurality of loops of a smaller diameter; a shape retaining member made from a sheet-shaped member such as cloth and spread inside the antenna element so as to maintain a spread state of the antenna element spread into a loop shape; and connection means for connecting the antenna element to an external device. Because the antenna element can be collapsed into a plurality of loops of a smaller diameter, the antenna apparatus can be reduced into a smaller size for carrying.
