| Abstract(in English) | The authors previously proposed a beam switching antenna consisting of a Butler matrix and a slot array integrated on a single-layer dielectric substrate. Short-slot couplers are used to construct the hybrids and the crossing couplers in the Butler matrix. The length of the coupler is determined by the difference of the phase constants between the TE_<10> and TE_<20> modes in the coupled region. This paper proposes a method to reduce the coupler length by making hollow rectangular holes near the side walls. We have confirmed theoretically and experimentally that the total size can be reduced to 48% and still obtain the conventional good dividing characteristics. |
