Disclosed is an antenna which has a simple structure and a small null angle, and which can achieve communication using a circularly-polarized wave. The antenna includes a conductive wire which is arranged in loops in such a way as to form a cross shape. The part at which two line portions projecting outward from the center portion define a right angle is included in the loop path of the conductive wire. This part allows the antenna to transmit and receive an electromagnetic wave in all directions and have a circular polarization characteristic.
