| Sumario: | [EN] This article describes a practical method to design waveguide tapers with smooth profile. A tapered waveguide, in general, is used to match different waveguide sections with the lowest possible reflection level. This method, based on Bernstein approximations, is used to achieve a reflection levels lower than the typical 20 dB in waveguide designs. The taper is designed with a prescribed length for bandwidths beyond the common frequency band of the end waveguide sections. An example of waveguide taper is compared with previous works in terms of reflection and curvature parameters. Finally, a prototype has been simulated and measured with excellent results. |
