“…To overcome the drawbacks of the conventional bulky waveguide and planar transmission lines, the concept of substrate integrated waveguide (SIW) has been reported and investigated since 2001 . It provides a low cost, low loss, high power‐handling capability, self‐shielded, and easy integration with planar circuits . For a compact design, the SIW structure occupies a large area and requires a technique to reduce its size.…”

“…2 It provides a low cost, low loss, high power-handling capability, self-shielded, and easy integration with planar circuits. 3 For a compact design, the SIW structure occupies a large area and requires a technique to reduce its size. Half-mode SIW (HMSIW) technique, which can be obtained by bisecting the SIW structure along the magnetic wall, achieves nearly 50% reduction in the size without deteriorating the performance of SIW structure.…”

In this paper, two ultracompact power dividers based on the substrate integrated waveguide (SIW) and half‐mode SIW (HMSIW) technologies loaded by complementary split‐ring resonators (CSRRs) are presented. The presented structures are designed based on the theory of evanescent mode propagation. To obtain a size reduction, the CSRR unit cells are etched on the metallic surface of the SIW and HMSIW structures. First, a two‐way HMSIW power divider is reported. In this circuit, the concept of HMSIW is utilized aiming at a further size reduction in addition to the size reduction by the CSRR unit cells. Then, a four‐way SIW power divider is designed so that the direct coaxial feed is used for the input port and microstrip transmission lines are used for the output ports. Both two‐way and four‐way SIW/HMSIW power dividers at 5.8 GHz covering WLAN are designed, fabricated, and measured. They respectively have 0.18 × 0.21 λg2 and 0.38 × 0.21 λg2 total size. A fair agreement between simulated and measured results is achieved. The measured insertion losses are 0.5 ± 0.5 and 0.6 ± 0.5 dB for the two‐way and four‐way SIW/HMSIW power dividers, respectively, in the operating band of interest.

“…In this study the design approach of modified Wilkinson power divider linked with 4-element of balanced antipodal Vivaldi antenna (BAVA) [16], [17] has been introduced. The paper is discussing a practical technique of Wilkinson power divider along with structural alteration by consuming conventional power splitter for feeding network [18][19][20]. This research based on two different stages of 1-to-2 way Wilkinson power dividers along with 3GHz to 10GHz range of frequency.…”

In this paper, design of compactand modified geometrical structure of 1-to-4 way ultra-wideband Wilkinson power divider used as a feeding network for 4-element of balanced antipodal Vivaldi antenna (BAVA) array has introduced. The proposed Wilkinson power divider has been designed and printed on low-cost Epoxy laminate substrate FR4 along with the thickness of 1.6mm and relative permittivity of ɛr =4.3 respectively. The transformation of power divider network which are based on bent corners as a replacement of sharp corners or edges used for the decrement in unintended radiation and employing a single radial stub on each branch to encounter the antenna-specifications. Further some adjustments in the dimension of stubs matching in order to increase the reflection of the power divider network. The design presents the model of a power divider and maintains an equal power splitting at different ports with practical insertion loss and conventional return loss below -10dB. The reasonable impedance matching has achieved at every single port with acceptable isolation performance values over the (3-to-10 GHz) frequency range. The divider as well as antenna elements design and its optimization are practicable via computer simulation technology (CST) simulation software. The experimental results are revealed to encounter the arrayspecifications under ultra-wideband frequency range..

A broadband eight-way substrate integrated waveguide (SIW) radial power divider/combiner with high-isolation is presented. The step probes are utilized to achieve broadband impedance matching and improve the return loss. What's more, the star structure based on microstrip circuit is employed to improve the isolation performance. A two-layer SIW radial power divider/combiner is designed, fabricated and measured. Good agreement between simulated and measured results is achieved for the proposed power divider/combiner. The measured results show that both bandwidths of the input and output port are 25% and 20% when their return loss are lower than −15 dB. The measured output isolation is greater than 17.5 dB from 5.75 GHz to 7.85 GHz and greater than 20 dB from 6.8 GHz to 7.9 GHz. The presented eight-way SIW power divider/combiner has the advantage of wider bandwidth, lower return loss and insertion loss, and higher isolation between the outputs.
