“…They present many excellent advantages, including wideband, low insert loss, high isolation etc. Hence, many reported articles have focused on the power dividers based on directional coupler, such as those in References 1‐10. Recently, the improved wideband three‐way waveguide power divider is widely applied owing to its outstanding advantages such as wideband, low insert loss, high return loss, high isolation and simple design.…”

In this paper, a directional‐coupler‐based wideband three‐way waveguide power divider is demonstrated. The proposed power divider consists of tapered rectangular waveguide, six‐port directional coupler and iron pentacar‐bonyl terminations. Its fractional bandwidth is 10.99% at 12.9 to 14.4 GHz. In addition, the return loss of all input and output ports is better than 20 dB and the isolation of the three output ports is more than 20 dB. Moreover, the insert loss is better than 5.19 dB including the power division ratio of 4.8 dB and the amplitude imbalance among the three output ports of less than ±0.4 dB. The experimental results agree well with the simulation ones, which indicates the validity of our method. With the above‐mentioned characteristics, the proposed device can be widely used in Ku band communication systems.

A study on the passive microwave components made by polymer additive manufacturing (polymer jetting) is presented. Different types of components (waveguides, couplers, power dividers, filters and antennas) are designed to be made in a single part. Using a simple and cost‐effective metallisation by applying silver paint, various prototypes with complex geometries have been manufactured to evaluate these proofs of concept and the robustness of the low‐cost approach to make microwave components. Different measurements show that the obtained filters can provide an acceptable unloaded Q factor of 400–500 for the operating frequencies of 12–22 GHz. Waveguiding structures such as a mode converter, which is used as a broadband antenna, have also notably efficiently worked up to the Ka band (36 GHz). Due to a remarkable accuracy of nearly 80 µm, the obtained results of the proposed coupler, power divider and antennas are consistent with the full wave simulations, which prove that the currently available three‐dimensional plastic printers can provide notably accurate prototypes to design original components.
