摘要
To solve the problem that it is difficult to install isolation resistors across each output port, a new five-way microstrip Wilkinson power divider with double-layer topology is developed. The isolation resistors are placed on the second substrate by using half-wavelength microstrip transmission lines with the introduction of Archimedean spirals to reduce the circuit size. To demonstrate the design method, a five-way equal power divider is designed; its size is optimized at the center frequency of 2.45 GHz. The fabricated sample has been tested. Measured results are in good agreement with simulations.
