This paper proposes a new antenna structure named MS-MPYA that consists of a multi-sector monopole Yagi-Uda array on a circular ground plane. To numerically analyze MS-MPYA and clarify mutual sector interaction when the antenna uses multiple sectors, the moment method which combines patch and wire models, is used in this paper. This paper introduces the following results. The beam width is reduced by 10.0 degrees in horizontal plane due to mutual sector interaction (compared to the single sector configuration). Setting metallic fin reflectors between each array is effective in eliminating the strong reflection that causes pattern unstability. The MS-MPYA realizes a low-profile multi-beam antenna that offers 30 degree beam with twelve sectors; the antenna height is 0.6 λ (λ: wave length), ground plane diameter is 10.1 λ, and array length is 3.5 λ. Experimental results confirm the accuracy of the analysis method used.
