“…Such a technique was also applied for return loss improvement . Over the last decade, the use of metamaterials has opened a new door in designing microwave and electromagnetics components . In Reference , the application of a π‐shaped transmission‐line coupled to a specialized metamaterial structure resulted in a power divider operating in three bands, while the overall footprint is significantly smaller than the conventional Wilkinson power dividers.…”

In this paper, a new neuro-based approach using a feed-forward neural network is presented to design a Wilkinson power divider. The proposed power divider is composed of symmetrical modified T-shaped resonators, which are a replacement for quarter-wave transmission lines in the conventional structure.The proposed technique reduces the size of the power divider by 45% and suppresses unwanted bands up to the fifth harmonics. To verify the concept, a prototype of the power divider has been fabricated and tested, exhibiting good agreement between the predicted and measured results. The results show that the insertion loss and the isolation at the center frequency are about 3.3 ± 0.1 dB and 23 dB, respectively.

“…One kind of design is that the single‐ended outputs are in‐phase. For example, the balanced‐to‐single‐ended power dividing networks based on ±90° structures or composite left‐ and right‐handed transmission lines . The other kind of balanced‐to‐single‐ended power divider is out‐of‐phase.…”

In this article, the filtering balanced‐to‐single‐ended power dividing networks are proposed. Except the fundamental functions of differential‐mode transmission, common‐mode suppression, and out‐of‐phase single‐ended output ports with isolation, the proposed designs show the advantages of wide controllable range of differential‐mode bandwidth, multiple transmission zeros (TZs), and wide bandwidth for high out‐of‐band suppression. The frequencies of TZs, bandwidth, isolation, and common‐mode suppression can be controlled by the parameters. For demonstration, three prototypes (Deigns I, II, and III) with two, four, or six TZs are implemented. The measured results show that design I (II and III) has an insertion loss of 0.38 dB (0.7 dB and 0.8 dB), an operating bandwidth of 12.5% (7.5% and 6.9%), and a bandwidth for 30‐dB out‐of‐band suppression of 0.06f0 (0.09f0 and 0.14f0). The isolation and common‐mode suppression inside the passbands of the three prototypes are all larger than 17 and 38 dB, respectively.
