PROBLEM TO BE SOLVED: To obtain a high gain circularly-polarized wave loop antenna which can receive a circularly-polarized wave incoming at a high-elevation angle. SOLUTION: A first loop element 10 having perturbation conductors 12 and 13 which can receive a circularly-polarized wave, and a second loop element 20 having perturbation conductors 22 and 23 are arranged while being spaced apart vertically by a predetermined distance. A beam of the circularly-polarized wave loop antenna 1 can have a high elevation angle because a reception signal of the first loop element 10 arranged above is delayed behind a reception signal of the second loop element 20 when they are compounded.
