“…Different designs have been developed, such as using irises/multiple posts in input and output waveguides [14,15], a partial-height post [16], a junction waveguide with an increased height [17,18,19] and a septum with matching iris [20,21,22,23]. Other studies proposed different types of power divider [24,25,26,27,28,29], using a circularly polarized TE11 mode [30,31], using two symmetric irises and a septum [32] and using substrate integrated waveguide [33].…”

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.

A novel TE01-TE20 mode converter is designed and fabricated by 3-D printing in this paper. It can realize high-efficiency (>97.5%) mode conversion in broadband from 27 to 40 GHz. Its weight is 0.011 kg only, and its coupling cavity normalized length is 0.39λ. An out-of-phase power divider is designed to verify the mode converter by observing the difference of output phase and flat frequency characteristics when connected to the mode converter. A sample converter with a power divider was then tested. Flat frequency characteristics for power dividing and anti-phase outputs are obtained in the working bandwidth to verify the mode converter with a good performance of mode conversion.

A novel wideband eight-way radial waveguide power combiner has been proposed in this paper. The proposed radial waveguide power combiner consists of a commercial N-type connector, a regular-octagon waveguide cavity, eight matching circuits, and eight coaxial-to-ridge waveguide transitions. The introduction of matching circuits is used to improve matching performance in the regular-octagon waveguide cavity. Besides, in order to guarantee the bandwidth performance and facilitate applications, eight coaxial-to-ridge transitions as output ports were also designed to connect ridge ports of the radial waveguide power combiner. Therefore, the overall performance of the proposed waveguide power combiner is enhanced over the wideband range. For validation, a sample eight-way radial waveguide power combiner has been designed, fabricated, and measured. The measured results show that the return loss (S11) and insertion loss (S21) are better than 20 dB and 0.5 dB, respectively, in the whole frequency range from 4 to 8 GHz (with 66.6% fractional bandwidth). The measured results reasonably agree well with the simulation ones. Compared with some other radial waveguide power combiners, the completed radial waveguide power combiner exhibits lower return loss, lower insertion loss, more compact size, and prominent bandwidth performance.
