✦ Synopsis
8.08 GHz is achieved. A maximum isolation of 40.9 dB is also obtained at 10.44 GHz.
4. Conclusions
In this article, a transmission line circuit model for an HMSIW Wilkinson power divider is presented. The scattering parameters of the power divider are derived using the power-current relation for waveguide impedance and even-and odd-mode analysis. Derived formulations indicate that the value of the shunt resistor can be adjusted to achieve an optimum isolation performance across a wide bandwidth. This method, which is applicable to any type of interconnect, serves as a rapid means to determine the initial design parameters of the power divider and its subsequent optimization. The S-parameters of an HMSIW power divider calculated using the presented approach are validated with full-wave simulations and measurements. Measured results show the maximum isolation of 40.9 dB at 10.44 GHz and the achievement of 71% 10-dB isolation bandwidth by choosing a 110-X branch resistor.
