Kertas kerja ini membincangkan teknik reka bentuk peluasan jalur bagi pengganding garis cawangan dwijalur dengan rangkaian padanan yang terdiri daripada langkah impedans dan stub litar pintas berdasarkan pendekatan kemasukan yang setara. Dengan menggantikan setiap talian penghantaran tangan kanan (RH-TL) dengan talian penghantaran kanan/kidal komposit (CRLH-TL), gandingan yang sangat rata pada lebar jalur relatif kira-kira 10% boleh diperolehi pada dua frekuensi operasi sewenang-wenangnya berbanding dengan pengganding talian cawangan CRLH-TL sebelumnya. Tambahan pula, dengan menambahkan stub litar terbuka berkala ke dalam RH-TL bagi pengganding talian cawangan CRLH-TL yang direka bentuk dengan rangkaian yang sepadan, keseluruhan saiz pengganding boleh dikurangkan kepada kira-kira 50%. Pengesahan teknik reka bentuk pelebaran jalur dan pengurangan saiz ini juga boleh ditunjukkan melalui simulasi dan eksperimen elektromagnet.

Abstract: This paper treats a band-broadening design technique of a dual-band branch-line coupler with matching networks composed of an impedance step and a short-circuited stub based on the equivalent admittance approach. By replacing each right-handed transmission line (RH-TL) with a composite right/left-handed transmission line (CRLH-TL), very flat couplings over a relative bandwidth of about 10% can be obtained at two arbitrary operating frequencies in comparison with previous CRLH-TLs branch-line couplers. Furthermore, by adding periodical open-circuited stubs into RH-TLs of the designed CRLH-TLs branch-line coupler with matching networks, the entire size of the coupler can be reduced to about 50%. Verification of these band-broadening and size-reduction design techniques can be also shown by an electromagnetic simulation and experiment.
