CONTRIBUTION TO THE STUDY, DESIGN AND PRODUCTION OF A MINIATURIZED ADJUSTABLE PHASE COUPLER FOR BEAM STEERING APPLICATIONS
|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 (cid:13)exibility, 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 veri(cid:12)ed by the results obtained by simulation and measurement. coupler with broadband bandpass response was proposed. In the same line, Muquaddar et al. [7] presented a novel branch-line coupler with improved bandwidth and reduced size, and in [8] a design of Full-360 ◦ Re(cid:13)ection-Type Phase Shifter was achieved using Trans-Directional Coupler with Multi-Resonance Loads. In this paper, we extend the ranges of phases to cover the most relevant used phases in any possible application, mainly 0, 45 ◦ , 90 ◦ , 120 ◦ and 180 ◦ . This can be achieved by introducing six varactor diodes to the traditional directional coupler to adjust it to the desired phase without compromising any of its given characteristics. The adjustable coupler will be used in a Butler matrix. A Butler matrix is a very advantageous beam-forming network due to its ability to form orthogonal beams in a simple design and is commonly found in microwave circuits.
