title = "A compact LTCC branch-line coupler using modified-T equivalent-circuit model for transmission line",
abstract = "In this letter, a compact branch-line coupler is proposed by making good use of the three-dimensional layout capability of the low-temperature co-fired ceramic (LTCC) substrate. This branch-line coupler is accomplished by using lumped-inductors and lumped-capacitors to realize the modifled-T equivalent-circuit model for the transmission line so that the circuit size may drastically be reduced. Specifically, a very compact LTCC branch-line coupler with a size of 0.079λ × 0.0717λ is implemented and carefully examined, where λ is the wavelength of the multilayer structure at the operating frequency f 0.",
