Abstract

This paper proposes a new small multisector antenna called MS-MPYA (multisector monopole Yagi-Uda array) for wireless LANs. MS-MPYA consists of a multisector monopole Yagi-Uda array on a circular finite ground plane. The horizontal radiation pattern of the MS-MPYA is largely determined by the multisector array setting effect. A numerical analysis shows that setting metallic fins between arrays is effective in eliminating the strong reflection that would otherwise cause pattern instability; when the metallic fins are set, the beamwidth is reduced in the horizontal plane due to mutual sector interaction. The MS-MPYA design method considers the variables of array length, ground plane length, reflector height, and fin length. We clarify that the MS-MPYA offers a much lower profile than corner reflector or horn antennas.
