Abstract
AbstractBased on transmission line theory, a 4‐way wideband coupled‐line Wilkinson power divider is designed by the authors, operating from 6 to 18 GHz. It is established by using a novel manufacturing technology with 3D stacked micro‐coaxial line, realising attractive advantages of low insertion (IL) loss and compact size. The simulated result shows that the proposed power divider of 23.5 × 14.46 × 0.9 mm obtains a maximum IL of 0.42 dB over the entire operating band. Measured results are obtained by connecting this micro‐coaxial power divider with printed circuit board, showing that the proposed structure is suitable for microwave communication systems.
