For the practical implementation of RF and microwave impedance matching networks, a widely employed solution-alternative to the use of classical impedance transformers-is based on tapered lines. This paper shows a simple method to design smooth tapers, that take into account the dispersion of the line and the required design bandwidth simultaneously. A planar taper has been designed in microstrip technology with the same length of classical ones but improving their performances. A waveguide prototype has been also designed with similar performance to a commercial one but with one third of its length. Both tapered structures have been obtained through optimization of very few parameters using the same design strategy. As a result, the reflection coefficient of the tapers can be optimally adapted to a given specific mask using the prescribed value of physical length. Experimental results for both tapers are included for validation of the proposed topologies and the related design method.

This paper presents guidelines for the design of square-tocircular waveguide transitions. Based on an algorithm developed for rectangular waveguide transformers, performances of initial and optimized transitions are presented. Although a direct transition from square to circular waveguide provides already a reasonable return loss, it is shown that more sections are required for broad-band and dual-band transitions. Verification of design and analysis procedures is provided through comparison with the commercially available field solver HFSS.
