Abstract
There is disclosed an antenna device having low side-lobe characteristics comprising a pair of array antennas having the same construction. Each array antenna has array elements equidistantly arranged. The center-to-center distance between the array antennas is so determined that the angle of the first zero point of the array factor determined by the center-to-center distance equals the angle of the first side lobe point of the pattern of each array antenna. The array antennas are electrically connected so as to become excited in phase.
