This paper introduces different types of N-way metamaterial radial power combiners/dividers. The metamaterial properties permit significant size reduction over a conventional N-way radial power combiner/divider. Metamaterial “MTM Technologies™” allow designing transmission lines with an electrical length of zero degree. The first design presented in this paper uses a 0° MTM line that reduces the size to one third of the conventional N-way radial divider. This size reduction improves overall performance by injecting fewer losses into the system and increasing the bandwidth of the radial power combiner/divider. Dual-band properties of Metamaterial are exploited in a second approach to design a dual-band MTM N-way power combiner/divider. In this second case MTM lines have a zero degree phase at a chosen frequency and 180° phase at a second chosen frequency which is not a multiple of the first one. This dual-band radial power combiner/divider is smaller than a conventional 180° single band radial power combiner/divider. Simulation and measurement data is presented in this paper for these different devices. |
