“…Table 3 shows the performance of the proposed BTB FPD and other reported BTB FPDs. The proposed BTB FPD based on the HMSIW-SSPP transmission line has a broader operating bandwidth than the BTB FPDs in [ 2 , 3 , 4 , 6 , 7 , 8 , 9 ], and it also possesses independent control of the passband’s lower and upper cut-off frequencies, making obtaining the desired frequency response easier. Although the SSPP BTB FPD in [ 5 ] achieves a 152% FBW and compactness, this proposed design has better IL, RL, and isolation than that of [ 5 ].…”

In this paper, a novel broadband balanced-to-balanced (BTB) filtering power divider (FPD) utilizing the half-mode substrate-integrated waveguide and spoof surface plasmon polariton (HMSIW-SSPP) hybrid transmission line is introduced. Initially, a new HMSIW-SSPP unit cell is proposed, demonstrating a lower upper cut-off frequency compared to the classical HMSIW-SSPP unit cell. Building upon this unit cell, a bandpass BTB FPD is devised employing dual-layer stacked substrates, enabling independent control over the passband’s lower and upper cut-off frequencies through specific physical dimensions. Additionally, the incorporation of isolation resistors and defected ground structures in the BTB FPD enhances differential-mode isolation and common-mode (CM) suppression between output ports. A manufactured and tested BTB FPD prototype validates this design method, showcasing a broad fractional bandwidth of 52.31% (6.72–11.48 GHz), output port isolation surpassing 14.25 dB, and transmitted CM suppression exceeding 34.05 dB.

In this article, a balanced filtering antenna array with quasi-Yagi performance is presented. The proposed design is composed of a balanced-to-single-ended power division network, two bandpass filtering units and a linear quasi-Yagi array including four elements. A steep differential-mode (DM) passband frequency response is obtained by introducing the triple-mode folded cross stubloaded resonators (FC-SLRs) in the power division network. The fractional bandwidth and center frequency can be controlled conveniently by adjusting the dimensions of FC-SLRs. Further, the design procedure is simplified due to the DM responses which are independent of the common-mode (CM) ones.The proposed antenna array with high gains, good CM rejections, and low cross-polarization levels is achieved. In addition, three radiation nulls are engendered on the sidebands to improve the selectivity. For demonstrating its feasibility, the balanced antenna prototype is fabricated and measured. The good performances of the proposed balanced filtering antenna array are observed.

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.
