“…Concerning the absorptive-type common-mode filters, a fractional bandwidth above 100 % was achieved in the implementations of refs. [51], [52], [79], [80], [82], [85], in some cases with very good common-mode absorption. Several of these filters are bidirectional.…”

“…Therefore, the reflected common-mode noise can be driven through the whole system and be the cause of unexpected radiation. To alleviate this problem, the so-called absorptive common-mode filters (A-CMFs) have been proposed in the last decade [51], [52], [53], [74], [75], [76], [77], [78], [79], [80], [81], [82], [83], [84], [85]. Such A-CMFs can absorb (or dissipate) the common-mode noise utilizing resistors or lossy materials, thereby preventing common-mode noise reflection, and hence, undesired radiation.…”

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.

“…Furthermore, the CMFs based on the electromagnetic band gap (EBG) are studied, where periodic patches are embedded in between the ground plane and another plane with the differential lines or periodic slots etched on ground/power plane [11,12]. Beside these reflective CMFs, a common-mode noise absorption CMF is explored [13], where the commonmode signal is absorbed instead of being reflected back to the input port during the common-mode stopband. The researchers have also presented effective approaches for the common-mode noise suppression by employing compensation inductance or capacitance at the bend of the differential lines [14].…”

The conventional quarter/half-wavelength common-mode filter (CMF) cannot work well for a differential stripline when there is no ground via. A new and effective viafree CMF design for the differential striplines is proposed in this study. An alternating high-low impedance structure is developed to increase the coupling between the stripline and the CMF, thus achieving a good filtering effect. A cascaded CMF design is further studied to enhance the stopband without deterioration of the differential signals. Both simulation and measurement results demonstrate the effectiveness of the proposed high-low impedance CMF. The significant advantage of the proposed CMF is its compactness and simplicity, which has almost no impact on the original layout of differential striplines.
