“…It is seen that the SIW power dividers in [9,10,23,24] provide slightly better isolation than the proposed prototypes due to the use of resistive elements in their design. The present prototypes achieve compact size and less insertion loss than reported SIW PDs [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24]. Therefore the proposed SIW DBPD exhibits the advantages of smaller circuit-area, low insertion-loss and acceptable isolation beneficial for dual-band applications.…”

“…The SIW power divider becomes a key component at millimeter wave band and widely used in array antennas, multiplexers and power amplifiers (PAs). In recent years, the development of SIW power dividers with low insertion loss, broadband, miniaturization has been attracted many researchers [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. A high isolation SIW power divider based on the fixed width lines has been designed [8].…”

In this paper, a novel design of highly compact power divider employing substrate-integrated waveguide (SIW) is proposed for dual-band applications. The double-ring asymmetric complimentary split-ring resonators (CSRRs) are utilized to obtain dual-band operation. The asymmetric double-ring CSRRs create mixed magnetic and electric coupling resulting two distinct resonating frequencies which exhibits bandpass behaviour below the resonating frequency of the cavity. The resonating passbands can be designed individually by varying the dimensions of the proposed CSRRs. In addition, the position of output ports can be varied to achieve arbitrary power division. To demonstrate the proposed analysis, three prototypes (two equal power division and one unequal power division) of dual-band SIW power dividers are designed and fabricated. Measurement performance provides a good consistency with that of simulated one. The circuit areas of the fabricated prototypes 1, 2 and 3 excluding microstrip transitions are 0.053λ g 2 , 0.088λ g 2 and 0.033λ g 2 , respectively. The proposed design process exhibits dual-band performance with smaller circuitarea, suitable isolation and hence appropriate for dual-band communication services.

“…The half-mode [22] and quarter-mode [23] SIW divider are employed for miniaturisation or other purposes, with the disadvantage of increased IL. As a result, the research on SIW dividers focuses on miniaturisation, increased isolation between dividing ports, and more complex multilayer or vertical structures [24,25]. There are very few SIW Y-type dividers with improved bandwidth feature in the standard enclosed, lossless, and three-port configuration.…”

An X‐band substrate integrated waveguide (SIW) balun, based on a Y‐type divider with enlarged bandwidth, is presented in this study. In most SIW Y‐type dividers, the undesired TE30 mode either leads to the deterioration of the in‐band reflection or constrains the bandwidth by a transmission zero. The cause of the transmission zero is analysed and the modes coupling, rather than the step impedance matching, is utilised to reduce its impact. In the traditional Y‐type divider, the frequency band is split by this transmission zero, while in the proposed wideband configuration, the co‐existences of the TE10 and TE30 modes are employed to combine the two non‐contiguous bands. A broadband balun is designed and fabricated, with the improved Y‐type wideband divider serving for the power‐dividing part. The dividing ports are connected to the reversely placed transitions, achieving inherent out‐of‐phase performance and good amplitude property. The measurement of the balun suggests a 43.94% bandwidth from 8.23 to 12.89 GHz, with 15 dB return loss. The measured amplitude and phase imbalance between two output ports are below 0.7 dB and ±3°, respectively. The performance of the fabricated balun is in agreement with the simulation, and it is promising for wideband applications.

“…Recently, a multilayer SIW power divider with embedded thick film resistive septum exhibits over 22 dB isolation over 18.5–22 GHz [6]. Another SIW power divider integrated with thick film resistive layer even shows 40% FBW with 20 dB isolation [7]. Nevertheless, their realization requires a costly and complex thick film fabrication process.…”

In this paper, a 3 dB H-plane substrate-integrated waveguide (SIW) power divider/combiner with improved isolation is reported. By adding two isolated ports into the Y-junction, it will perform like a multi-port coupler, so that the isolation between its dividing ports can be effectively improved as the newly-added ports are properly matched. To verify the availability and effectiveness of this concept, two prototypes, one is terminated by coaxial terminations and the other is loaded with lumped resistors, are developed. Their measured results are separately in good agreement with their corresponding simulations. Meanwhile, isolations better than 16 dB with fractional bandwidth (FBW) of 35 and 25% are achieved, respectively, as well as low phase and amplitude imbalances. Compared with some reported similar SIW power dividers, the proposed ones exhibit wider FBW with similar isolation, insertion loss, phase, and amplitude balance performance.
