Miniaturization of Broadband Wilkinson Power Dividers
Received Jan 5, 2018 Revised Mar 3, 2018 Accepted Mar 20, 2018 This paper proposed three modified Wilkinson power dividers in order to achieve a size reduction and a wide bandwidth. The first structure presented the power divider using compact folded step impedance transmission lines rather than the uniform microstrip line design for operating center frequency of 3 GHz. The second structure sho...
متن کاملDual Band Wilkinson Power Dividers Using T-Sections
This paper presents analysis and design of a dual band Wilkinson power divider for wireless applications. The design is accomplished by transforming the lengths and impedances of the quarter wavelength sections of the conventional Wilkinson power divider into dual band T-shaped sections. Simple design equations for the basic geometry are given. The designed dual band Wilkinson power divider str...
متن کاملMiniaturization of Wilkinson Power Dividers by Using Defected Ground Structures
It is proposed that the application of defected ground structures (DGS) and electromagnetic bandgap (EBG) reduce the phase velocity, increase effective permittivity of microstrips and reduce the effective the wavelength which eventually lead to the reduction of overall length of Wilkinson power dividers. Furthermore, the adjacent strip lines may approach each other, which cause coupling problem...
متن کاملMiniaturized Gysel Power Dividers Using Lumped-Element Components
This letter presents miniaturized Gysel power dividers using lumped-element components. The characteristic impedances of all the equivalent transmission lines in these dividers are fixed to the same values based on even and odd mode analysis, thus simplifying the design procedure and miniaturizing the Gysel power dividers. The ideal divider designed at a frequency of 590MHz exhibits power split...
متن کاملEffect of Adding Input and Output Impedance Transformer on Wilkinson Power Dividers Performance
Even though the two-stage Wilkinson N-way power divider is simple to design, realize and test, It has been used with strict restrictions in design and fabrication because it requires a very high impedance microstrip line, i.e., extremely low aspect ratio W/H or very thin line conductor width. To overcome this limitation in realizable characteristic impedance a quarter-wave length impedance tran...
