“…Several reports exist on FPDs based on transmission lines and planar multimode resonators using printed circuit board (PCB) technologies. [2][3][4][5][6][7][8][9] However, it is difficult to implement miniaturized mm-wave circuits on PCBs due to conductor loss and fabrication error. Radiation loss is also an issue since the length and width of circuit elements are quite small in mm-wave.…”

We present a compact, filtering power divider (FPD) using integrated passive device technology (IPD) for mm‐wave applications. Our proposed FPD design integrates quarter‐wavelength coupled‐resonator bandpass filters with a Wilkinson power divider, using size reduction techniques. Coupled coplanar waveguides provide excellent coupling while occupying a small area, and metal‐insulator‐metal capacitors offer the required λ/4 phase shift without length extension. The center frequency of the filtering power divider/combiner (FPD/C) is located at 30‐GHz. We demonstrate our FPD design by fabricating four prototypes with parameter variations. The insertion loss, fractional bandwidth, and size of the FPD/C designed in this study are from 2.56 to 3.3 dB, from 9.67% to 19.4%, and from 0.592 to 0.220‐mm2, respectively. In addition, the return loss of all models at the center frequency is 28.5 dB or more, and the isolation is 16.6 dB or more.

“…Due to its ability to both filter and distribute power, the microwave filtering power divider (FPD) has attracted a lot of attention from the wireless communication research community in recent years [1][2]. In a Wilkinson power divider (WPD), a passband filter structure was used in place of a quarter-wave transmission line (QTL) to get both the power division response and filter response [3][4][5]. There have been a number of high-performing single passband FPDs grounded on WPD structure, substrate-integrated waveguide (SIW) configuration, and dual-composite right-left handed (D-CRLH) structure that has been studied in the past [6][7][8].…”

This proposed work describes a miniaturized and simple power divider that uses coupled lines for triple-band filtering. The intended setup included an isolation resistor connecting the output feed lines through Structure-3 and coupled line-based microstrip resonators connected to the input feed line. The presented power divider achieves three passbands with a filtering response. The first and second passbands are achieved by the coupled line that includes Resonator-1 and Resonator-2 of the proposed structure. The third passband is realized due to Resonator-3. Furthermore, by varying the structural parameter of the designed triple-band filtering power divider, the resonance frequencies of all three passbands can be controlled because of changes in their equivalent lumped parameters. The resonance frequency mainly depends on its equivalent inductance and capacitance value. For validation of the simulation result, the filtering power divider structure has been fabricated and tested. The experimental results denote that the prototype has a fractional bandwidth (|S21|<-3 dB) of about 20.0 % (1.1 GHz to 1.35 GHz), 37.0 % (2.0 GHz to 2.9 GHz), and 15.0 % (3.25 GHz to 3.8 GHz) respectively for first, second and third pass-bands. This arrangement shows isolation above 18 dB for all three bands with a downsized of 0.1λg × 0.12λg (25 mm × 30 mm) according to the operating frequency of the first frequency passband. The triple band performance of the developed component shows a good input reflection coefficient. The operating frequencies, which are suitable for the application of L-band, WLAN, sub-6 GHz band of 5G, which include 1.23 GHz, 2.41 GHz, and 3.55 GHz

“…Therefore, for achieving multiple rejections and keeping a compact size, it is highly demanded to build multifunctional devices including splitters integrated with multiple band-rejection filtering functions. In [37][38][39][40][41][42][43][44], power splitters integrated with a bandpass response were investigated widely based on microstrip and composite right/left-handed (CRLH) technologies. Multiple studies have reported explanations of the mechanism of dividing the SSPPs and designed efficient power splitters based on SSPPs.…”

In this paper, a new kind of spoof surface plasmon polariton (SSPP) beam splitter integrated with band-rejection filtering functions is presented. Firstly, the mechanism of single-band rejection phenomena of the SSPP transmission lines (TLs) with and without T-shaped decorations are revealed through dispersion analyses. Based on the single-band rejection filter, multi-band rejection filters are further designed by introducing different intervals between the symmetric T-shaped decorations. Furthermore, we construct a compact Y-shaped beam splitter integrated with a broadband band-rejection filtering function using the SSPP TLs, which consists of an SSPP TL with rectangular grooves and two filtering branch SSPP TLs. Multiple band-rejection integrated beam splitters can also be realized by incorporating different intervals between the T-shaped decorations. The integration of the SSPP beam splitter and band-rejection filter offers compact areas, lower insertion loss and controllable passband features. It is strongly believed that that the proposed idea will raise promising possibilities in the integration of multiple microwave functions in the same component, e.g. filtering antennas, filtering switches, multifunctional radiofrequency (RF) passive and active components capable of performing several RF analog signal-processing functions in the same circuit volume, and so on.
