“…In recent years, fourth-generation (4G) and fifth-generation (5G) wireless applications have been experiencing fast development [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Signal crosstalk, interference, and high costs have a big effect on the rapid development of radio frequency (RF) and microwave (MW) devices, while common-mode signal causes radiation power loss of up to 25% of the input power in the millimeter-wave (mmWave) spectrum (26)(27)(28)(29)(30)(31)(32)(33)(34)(35)(36)(37)(38)(39)(40) [17,18]. Over the last decade, many differential-fed devices, which provide high protection to interference signals, low RF noise, and a good degree of freedom, were increasingly in need of more attention and further studies [19].…”

“…So far, a few review papers have been introduced on the scop of balanced filters [36,37]. Arbelaez-Nieto et al [36] reviewed and studied some basic concepts related to microwave balanced bandpass filter structures and discussed some alternative methods to design, simulate, and measure differentially fed microstrip BPFs. To simplify the design procedure for other researchers, the paper has presented the step by step developments of planar differentially driven BPFs.…”

Differentially driven devices represent a highly promising research field for radio frequency (RF), microwave (MW), and millimeter-wave (mmWave) designers and engineers. Designs employing differential signals are essential elements in low-noise fourth-generation (4G) and fifth-generation (5G) communications. Apart from the conventional planar MW components, differential-fed balanced microstrip filters, as promising alternatives, have several advantages, including high common-mode rejection, low unwanted radiation levels, high noise immunity, and wideband harmonic suppression. In this paper, a comprehensive and in-depth review of the existing research on differential-fed microstrip filter designs are presented and discussed with a focus on recent advances in this research and the challenges facing the researchers. A comparison between different design techniques is presented and discussed in detail to provide the researchers with the advantages and disadvantages of each technique that could be of interest to a specific application. Challenges and future developments of balanced microstrip bandpass filters (BPFs) are also presented in this paper. Balanced filters surveyed include recent single-, dual-, tri-, and wide-band BPFs, which employ different design techniques and accomplish different performances for current and future wireless applications.3 of 25 between these designs follow each section. Section 6 shows the challenges and future development of differential-fed microstrip BPFs. Finally, Section 7 presents the conclusion of our review. Single-Band Differential Microstrip BPFsRecently, many single-band differential planar BPFs based on different techniques have been reported [39][40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56]. The main difference between these designs is the structures utilized. Several types of resonators and techniques can be used to obtain a single-band differential planar BPF with different performance. Generally, the common-mode noise suppression is an interesting topic for high-speed and high-frequency wireless applications. The common-mode noise signals can degrade the differential-mode transmitted signals as well as the entire power of such wireless applications. To suppress the common-mode signals, some researchers and engineers have proposed the use of a series of combinations of single-band differential-fed planar filters and transmission lines [39]. However, this technique will lead to a large area and so not suitable for new demands of compact systems. However, Ebrahimi et al. have proposed a new balanced BPF using dumbbell-shaped defected ground structures (DGSs) [42]. The proposed DGS resonator provides the option of implementing higher-order differential filters. Also, in comparison with similar techniques such as S-shaped complementary split-ring resonators (CSRRs), which have similar structures in common-mode and differential mode transmission [39], differential filters based on DGSs provide high common-mode attenuation by utilizing two separate equiv...

“…As is described in Ref. [5], balanced filters are designed in way that is similar to the one used for single-ended filters; the differential mode (DM) of the filter is obtained from the design parameters, the characteristics of the resonators and the feeding structures, whilst the CM response, is normally optimized by using additional structures like Defected ground structures (DGS) [6], lumped components [7], feeding structures loaded with stubs [8] or complementary split rings (CSR) [9,10]. Traditionally, the design of a balanced filters is a process, where the behavior under CM and DM are taken into consideration at the same time, along the entire designing process.…”

A novel method to obtain balanced structures is introduced. The balanced behavior of a single‐ ended structure is achieved by combining two stages of the single‐ended device, by means of a new common mode suppression network (CMSN). As an example, a conventional single‐ended balanced bandpass filter (BPF) was designed, and then transformed into a balanced bandpass filter (BBPF). Around the design frequency, the differential mode (DM) of the balanced structure inherits the performance of the single‐ended filter, whist suppressing the common mode (CM) signals more than 20 dB. Additionally, the out‐of‐band response of the single‐ended filter is improved in the balanced prototype by attenuating the first spurious frequency from 0 dB to 20 dB. Good agreement between simulated and experimental results is obtained. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2831–2833, 2016

A balanced bandpass filter (BBPF) with high common‐mode rejection (CMR) and extended differential‐mode (DM) stopband is presented. It is based on miniaturized Pi‐network ring resonators with loaded inductors. This structure permits the design of the common‐mode (CM) and DM resonances independently, which gives plenty of flexibility when designing the filter. Stubs are added along the symmetry plane to improve the CMR. A microstrip BBPF is designed at 921.7 MHz with a fractional bandwidth of 8.4% and a DM stopband of 10.13 f 0 ${{\boldsymbol{f}}}_{{\bf{0}}}$ for S21 < −30 dB. The CMR is better than −20 dB up to 10 f 0 ${{\boldsymbol{f}}}_{{\bf{0}}}$.
