PROBLEM TO BE SOLVED: To improve gain of antenna, by making the whole body compact and preventing interference of primary radiators arranged adjacently. SOLUTION: The antenna includes an electric wave convergence part 2 for converging an incident electric wave from different directions to a plurality of focal points, and a plurality of primary radiators 1 arranged at the plurality of the focal points of the electric wave convergence part 2. The primary radiator 1 has a dielectric antenna 4 and receives the electric wave focused on the focal point of the electric wave convergence part 2 by using the dielectric antenna 4.In addition, the dielectric antenna 4 is an eccentric dielectric antenna 4, of which a phase center of received electric wave is capable of shifting to a direction crossing with the propagation direction. The eccentric dielectric antenna 4 is arranged at a focal point of the electric wave convergence part and receives the electric wave converged at the focal point of the electric wave convergence part.
