Paper title: MICROSTRIP NON-UNIFORM TRANSMISSION LINES TRIPLE BAND 3-WAY UNEQUAL SPLIT WILKINSON POWER DIVIDER

Author(s): DERAR HAWATMEH, NIHAD DIB, KHAIR ALSHAMAILEH,

Abstract:

In this paper, we propose a non-uniform transmission lines (NTLs) 3-way triple band unequal split Wilkinson power divider (WPD). First, three impedance-varying transmission lines matched at 0.5, 1.25, and 2.0 GHz are designed in the even-mode analysis. Then, three NTL transformers are used to match the output ports to the 50 Ω connectors. Finally, the values of the isolation resistors (both in planar and non-planar configurations) are optimized to achieve an acceptable output ports matching and isolation at the desired frequency bands. To verify the underlined procedure, a triple band divider with power division ratios of 40 % at port 2 and 30 % at ports 3 and 4 is designed and simulated using two full-wave electromagnetic (EM) simulators. Simulation results show input/output ports matching and isolation less than 20 dB and transmission losses of 3.98 0.5 dB and 5.23 0.5 dB at the design frequencies.
