This paper provides an overview of balanced (or differential-mode) structures operating at microwaves, including common-mode suppression filters, balanced filters and circuits with intrinsic common-mode suppression, and differential-mode sensors. The increasing interest for balanced structures within the framework of communication circuits and sensors, related to their major robustness against electromagnetic interference (EMI), noise, and environmental factors, is duly justified. Then the paper reports various approaches for the implementation of common-mode suppression filters, balanced filters and circuits (including narrowband and wideband filters, multi-band filters, power dividers, couplers and phase shifters), and differential-mode sensors (mainly devoted to the measurement of permittivity and related variables). Rather than providing a detailed analysis of the different considered implementations/approaches, the main goal of this review paper is to discuss, and compare in some cases, the main proposed strategies (pointed out in the up-to-date state-of-the-art) for optimizing the performance of the various differential-mode devices under study.

“…As known, due to the difficult implementation of high impedance MSLs, large PDRs are usually hard to be achieved for some reported unequal FPDs [25,26]. To solve this problem, various coupling structures are integrated into PDs to obtain arbitrary ratio and filtering response simultaneously [27,28]. However, multiorder coupling structures are usually required to be investigated to further extend the bandwidths of these designs.…”

Design of compact planar power divider with wideband bandpass response and high in‐band isolation

In this study, a compact planar power divider (PD) with wideband bandpass response is proposed based on a coupled three-line filtering prototype. With two back-to-back microstrip feeding lines and a coplanar waveguide resonator located in the middle ground plane, the filtering structure is constructed. According to the synthesis approach, the proposed filtering structure can achieve an equal in-band ripple response with three transmission poles and four out-of-band transmission zeros. In order to make the proposed PD inherit the designed filtering performance, one of the output lines in the filter network is modified to realize a 50 to 25 Ω impedance transformation in the passband first. Then, for good in-band isolation and impedance matching at output ports, the modified output line is split into two separated lines by a slot so that a lumped resistor can be loaded at the ends of the two separated output lines. By properly setting the slot width and the resistance with guidance, high isolation level over an ultra-wide passband is attained. For demonstration, three cases of the PDs with different bandwidths are designed on the basis of the corresponding filter designs. Finally, two bandpass PDs are fabricated and tested to verify the design concept.This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

“…Reviewing all the relevant literature, the most balanced FPDs are mainly realized by using microstrip structures, such as H‐type resonators, 8 short‐stub‐loaded resonators, 6 dual‐mode ring resonators, 11 and patch resonators 2,3 . Nevertheless, these designs commonly suffer from high loss and low power processing capability and can only work in the lower frequency system 2 .…”

“…[2][3][4] Accordingly, the fusion design of balanced FPD, which has several advantages, such as low cost, low loss, miniaturization, and high integration, has been a hot topic recently in modern wireless communication systems. Following this trend, balanced FPD using the microstrip [5][6][7][8] and substrate-integrated waveguide (SIW) 9,10 have been developed, allowing easy connection with RF systems.…”

A compact balanced‐to‐balanced (BTB) filtering power divider (FPD) with in‐band common‐mode (CM) suppressions based in a single‐layer substrate‐integrated waveguide (SIW) is presented in this article. This FPD mainly consists of one full‐mode and two half‐mode SIW cavities where each cavity's differential‐mode (DM) and CM are designed reasonably. The filtering DM signals to dual‐ports power division is realized with a simple and compact configuration. Moreover, the CM signals can be naturally rejected without any additional isolation circuits. Ultimately, the BTB FPD with a center frequency of 10.5 GHz is designed, fabricated, and measured to verify the proposed design concept, which shows below −15 dB 6% DM filtering fractional bandwidth (FBW). The CM transmission is suppressed below −22 dB over 28.6% FBW. The proposed design exhibits the advantages of compact size, simple design, low loss, planarity, and multi‐function fusion.
