A new type of antenna coupled Y-branch with the advantages of low branching loss and short coupling length (hence, compact size) is proposed. This structure is free from the critical fabrication requirements that are associated with the directional coupler type power dividers and 3-dB couplers. There is no need for any extra bending elements (hence no bending loss), when this structure is used as a 3-dB couplerlpower divider of the Mach-Zehnder type switch. Detailed theoretical analysis (both two-dimensional and three-dimensional) is carried out.
