摘要

在本文中,我们介绍了一种小型化的可调耦合器的设计和生产,优化尺寸为长48毫米,宽31毫米。该耦合器提供了覆盖所有相位的可能性[0,45◦,90◦,120◦和180◦]。为了实现这一点,所提出的耦合器可以通过实现六个SMV2019-079LF二极管来调整,这些二极管允许从一个相位转换到另一个相位。在相移方面,这种新的(cid:13)灵活性可以大大提高这种小而高效的耦合器的多功能使用,特别是与以前改进的相移耦合器相比,这些耦合器仅限于一个或两个相。仿真和测量结果验证了该方法的高性能和高效性。提出了宽带带通响应耦合器。在同一条线上,Muquaddar等人提出了一种新的分支线耦合器,具有改进的带宽和减小的尺寸,并且在[8]中,使用具有多共振负载的跨方向耦合器实现了Full-360◦Re(cid:13)选择型移相器的设计。在本文中,我们扩展了相位范围,以涵盖任何可能的应用中最相关的使用相位,主要是0,45◦,90◦,120◦和180◦。这可以通过在传统的定向耦合器中引入六个变容二极管来实现,以将其调整到所需的相位,而不会影响其给定的任何特性。可调耦合器将在巴特勒矩阵中使用。巴特勒矩阵是一种非常有利的波束形成网络,因为它能够以简单的设计形成正交波束,在微波电路中很常见。

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.
