Abstract

PURPOSE:To offer a plane and compact conical beam array antenna, by arranging plural microstrip antennas in the center and on a circle around this center and adjusting the feed amplitude and the phase of each antenna. CONSTITUTION:A metallic substrate 11 is arranged on one face of a dielectric plate 10, and round metallic plates 9 which have center pins 12 and feeding pins 13 and 13' to constitute radiation elements are arranged in the center and on a circle around this center on the other face of the plate 10, thus forming 7 two- point feed round microstrip antennas. A power distributing circuit constituted with a microstrip line is used for feed to each radiation element, and the feed amplitude ratio of the round metallic plate 9 in the center to each of other 6 round metallic plates 9 is set to 6:1, and feeding is so performed that the phase of the radiation element in the center is opposite to the phase of each radiation element around it. Thus, the radiation electric field in the direction of the board- side is cancelled to obtain conical beams.
