Novel low cost 1-to-4 Microstrip Wilkinson Power Divider

A Wilkinson power divider with improved bandpass filtering and high isolation performance is proposed. These characteristics are achieved by replacing the quarter-wavelength transmission line in the conventional coupled line Wilkinson power divider with quarter-wavelength side-coupled ring (QSCR). Additional features such as DC blocking between arbitrary two ports, single-layer via-less structure for low-cost fabrication and convenient integration (as only one isolation resistor required) are highlighted. A 2-GHz Wilkinson microstrip power divider with a fractional bandwidth of 4% has been fabricated and experimentally characterized. The consistency between simulated and measured results validates the effectiveness of our proposed design.

Wilkinson Power Divider

In this paper, design of compactand modified geometrical structure of 1-to-4 way ultra-wideband Wilkinson power divider used as a feeding network for 4-element of balanced antipodal Vivaldi antenna (BAVA) array has introduced. The proposed Wilkinson power divider has been designed and printed on low-cost Epoxy laminate substrate FR4 along with the thickness of 1.6mm and relative permittivity of ɛr =4.3 respectively. The transformation of power divider network which are based on bent corners as a replacement of sharp corners or edges used for the decrement in unintended radiation and employing a single radial stub on each branch to encounter the antenna-specifications. Further some adjustments in the dimension of stubs matching in order to increase the reflection of the power divider network. The design presents the model of a power divider and maintains an equal power splitting at different ports with practical insertion loss and conventional return loss below -10dB. The reasonable impedance matching has achieved at every single port with acceptable isolation performance values over the (3-to-10 GHz) frequency range. The divider as well as antenna elements design and its optimization are practicable via computer simulation technology (CST) simulation software. The experimental results are revealed to encounter the arrayspecifications under ultra-wideband frequency range..

Equal Split

This paper deals with the design and simulation of unequal 5-way Wilkinson power divider used for Electronic Warfare (EW) applications. The frequency range of operation intended for this design is 6 GHz to 18 GHz. The proposed Wilkinson power divider is designed on a low cost FR-4 substrate having height of 1.5mm, relative permittivity of 4.4 and loss tangent of 0.02. The design occupies a size of 11mm x 33 mm x 1. 5 mm. Equal split Wilkinson power dividers are utilized for implementation of this design. High isolation has been obtained throughout the frequency range of 6 GHz to 18 GHz. The design procedure is discussed. The simulated results are presented by using ADS simulation software.
