Power Divider Based on Broadside Slot-Coupled Lines [PDF]

Journal of Electromagnetic Engineering and Science
This paper proposes a power divider composed of a broadside slot-coupled line with microstrips located on the top and bottom surfaces, a ground plane slot at the center, and a resistor for improved isolation. Two- and four-way dividers are designed based

Power divider with various power dividing ratios

Electronics Letters, 1999
A new power divider which has a completely planar structure and has various output power ratios is presented. This divider does not need any internal isolation resistors, and has almost perfect matching at all ports and perfect isolation characteristics.

Reconfigurable Power Divider-Enabled Dynamic Hybrid m-MIMO Transmitter

IEEE Open Journal of the Communications Society, 2022
A promising solution for massive Multiple-Input Multiple-Output (m-MIMO) systems is Hybrid digital-analogue (HDA) beamforming as it offers a balanced trade-off between energy efficiency (EE) and spectral efficiency (SE).

Generalized Symmetrical 3 dB Power Dividers With Complex Termination Impedances

IEEE Access, 2020
The paper introduces a class of two-way, 3 dB narrowband power dividers (combiners), closed on complex termination impedances, that generalizes a number of topologies presented during past years as extensions of the traditional Wilkinson design. Adopting
