A compact high-efficiency power divider/combiner based on quadruple-ridged waveguide

In this paper, a novel H-plane T-junction waveguide power divider that can operate on the entire W-band is in troduced,it can save more space in many applications. It solves the problem that the traditional Hplane T-junction waveguide power divider cannot cover the entire W-band and the reflection coefficient is less than −20 dB. A H-plane T-junction power divider for the size of WR-10 waveguide are designed and fabricated used a blocking plate, two grooves and a stepped input matching transformer. The measured results agree well with the simulations and It is suitable for the whole frequency band of W, and the reflection coefficient is less than −20 dB. The optimized design size can also be used for other waveguides.

“…Several microwave and millimeter-wave passive components based on substrate integrated waveguide (SIW) technology have been studied and published, such as power divider, coupler, filter, phase shifter, antenna, etc [1,2,3,4,5,6,7,8,9,10]. The most prominent advantages for SIW are its simple structure, low radiation, low insertion loss, and low cost [11].…”

In this letter, a novel 3-D empty substrate integrated waveguide (ESIW) phase shifter with equal length has been proposed. The vertical transitions have been introduced into 3-D ESIW phase shifter in the propagation path. Based on it, the different total lengths of phase shifters in the propagation path and the equal total lengths of phase shifters in the external structure are compatible. The phase shifter consists of multi-layer PCB: top layer, interlayer, middle layer, ESIW PCB, and bottom layer. The theory and design process of ESIW phase shifter have been explained and discussed in detail. To demonstrate its feasibility, the 3-D ESIW phase shifters with equal external length are designed, manufactured and measured. Final results show that the phase shifts of 45.2°±3.7° and 89.7°±4.7° can be achieved over the entire Ka-band. Besides, the return losses and the insertion losses are better than 12.5 dB, and 1.9 dB, respectively.

“…Among them, waveguide T-junction (E-plane [1,2,3] or H-plane [4,5,6]) power dividers are often used for their simple and compact structures. In practical application, the performance of the power divider, especially the phase difference between the output ports, affects the entire system.…”

2018

A novel planar E-plane waveguide power divider with extra 180°phase difference and full bandwidth is proposed. It is basically an E-plane waveguide T-junction power divider with its input port rotated around its axis by 90°and arranged symmetrically to form a planar structure. A sample power divider is then designed, fabricated and tested. The test results indicate that, in a relative bandwidth of 40%, the reflection coefficient is lower than −20 dB and the extra phase difference between the two output ports is 180°within an error of ²1.5°.
