To provide a compound element for a radio relay device antenna and a dipole array circular polarized antenna using it.
The compound element for the radio relay device antenna includes: a pair of parallel parts vertically arranged apart in parallel each other; a radiation part arranged at right angle with the pair of parallel parts and connecting each end of the pair of parallel parts; legs extending from the radiation part; and a plurality of electric supply members 550, 560 respectively connected to a plurality of radiation members 510, 520, 530, 540 arranged apart each other at the predetermined angle, and mutually-opposed radiation members out of the plurality of radiation members 510, 520, 530, 540. The dipole circular polarized antenna includes the plurality of compound elements for the radio relay device antenna arranged at the predetermined interval. An electric supplying method capable of improving a polarized wave ratio to minimize interference by the reflected wave, and for expanding a service area of the antenna to expand a service area of the antenna to simultaneously resolve an impedance matching and a generation of the circular polarized wave.
