Abstract

In this article, we present the design and production of a miniaturized adjustable coupler with optimized dimensions of 48 mm in length and 31 mm in width. This coupler offers the possibility of covering all phases [0, 45°, 90°, 120° and 180°]. To be able to achieve this, the proposed coupler can be adjusted through the implementation of six SMV2019-079LF diodes which allow shifting from one phase to another. This new flexibility, in terms of phase shifting, can greatly improve the multifunctional use of this small and efficient coupler, in particular, in comparison with previously improved phase shifting couplers which are limited to one or two phases. The high performance and efficiency have been verified by the results obtained by simulation and measurement.
