“…The research on wide-band and ultra-wideband systems is an attractive topic for current and future wireless applications due to the preferable functions to deal with high data rate transmissions. Wide-band and ultra-wideband BPFs are one of the fundamental elements of wide-band MW/RF communications, which has been deeply investigated in the literature [79][80][81][82][83][84][85][86]. Nevertheless, there has been little attention paid to wide-band and ultra-wideband differential microstrip BPF designs in the past few years [87][88][89][90][91][92][93][94][95][96].…”

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 can be observed, its configuration is composed of a rectangular-ring stub loaded with parallel-coupled lines and inverted T-shaped EBG resonator. While designing BPFs, one of the challenges is to design the filter in a compact area with high performance [19][20][21][22][23][24]. It is designed on a low-loss Rogers 5880 dielectric.…”

A new design of band-pass filter (BPF) with variable dual notched bands characteristic is introduced for ultra-wideband (UWB) applications. The configuration of the proposed BPF contains a rectangular-ring stub loaded with parallel-coupled lines and an inverted T-shaped electromagnetic band-gap (EBG) resonator is proposed in this letter. It is designed on a Rogers 5880 substrate with properties of ε= 2.2, δ= 0.0009, and h=1 mm. The proposed BPF exhibits a wide usable fractional bandwidth from 3.1 to 10.6 GHz and two-frequency notch-bands at 5 and 8 GHz. Due to the simple configuration and excellent characteristics of the presented design with tubule dual notch function, the proposed BPF is useful to be used in UWB communication networks.

“…Thus, microstrip antennas with filtering performance, high gain, high isolation, high front-toback ratio (FTBR), stable radiation pattern, good common-mode (CM) rejection level and unidirectional radiation pattern in the planar configuration simultaneously are necessary for 5G applications [22][23][24][25][26][27]. Recently, dual-polarized and differential-fed techniques have been extensively introduced to improve the performance of the microwave and RF systems [28][29][30]. Different differential-fed antennas have been reported, such as planar antennas [31][32][33][34], magneto-electric dipole antennas [35,36], 3D-backed antennas [37], and so on.…”

In this article, novel high-gain differential-fed microstrip reconfigurable filtering antenna with high common-mode rejection is presented. A pair of probe feeding port is utilized to provide differentially exciting signals. The filtering response is achieved by introducing four symmetrical open-loop ring resonator slots on the top layer surrounding the excitation ports of the patch antenna. The resonators can produce nulls at the high edge of the passband bandwidth with high gain and wide stopband characteristics. The filtering antenna is designed, simulated and optimized using computer simulation technology (CST) software with Rogers TMM3 substrate and a relative dielectric constant of 3.45. Also, the antenna has a single layer substrate with a height of 0.035 of the free space wavelength and operating at 2.6 GHz and 3.5 GHz for 4G and 5G applications, respectively.
