This paper presents the analysis, design, built and testing of a new compact 3 dB power divider operating across a wideband frequency range, with a 2.56 GHz center frequency. The proposed divider, consisting of three ports, is constructed using an FR4 substrate, with overall dimensions of 45×40×1 mm3. The frequencies with the best S21 and S31 results are recorded with a magnitude of -3.04 dB at 2.56 GHz. The simulated input match (S11) displays nearly − 30 dB at 2.56 GHz, with a -10 dB bandwidth extending from 1 to 4 GHz, resulting in a total bandwidth of 3 GHz. Hence, the proposed power divider emerges as a strong candidate for applications in both the L- and S-bands. The measured data exhibit strong agreement with the simulation results. The originality of this study lies in achieving high performance within such compact dimensions at an affordable cost, thereby eliminating the complexity that can lead to manufacturing errors. Additionally, it is demonstrated through a comparative table that the proposed power divider exhibits superiority over similar ones found in the literature.

A modified Wilkinson power divider (PD) with improved inband performance and compact size is proposed in this paper. Compared with conventional Wilkinson PD, such structure features with an additional shorted stub on the output port, which can introduce an extra transmission pole for in-band performance enhancement. Besides, the proposed Wilkinson PD adopts meander line for compact size. Furthermore, the isolation resistor is achieved with thin film resistance technology to avoid welding tolerance. To verify the mechanisms mentioned above, a modified Wilkinson PD operating at 7 GHz is designed and fabricated in size of 8.2mm×8.8mm (0.2𝜆 𝑔 ×0.19𝜆 𝑔 ), with significantly benefit of compact, wide-band, low loss and well in-band loss flatness characteristic. The measured fractional bandwidth (FBW) is 57.1% (i.e., 5-9 GHz) with insert loss of 3.2-3.4dB. Meanwhile, the return loss is less than 15dB.
