Design of a 64-Way 6-18 GHz Wilkinson Stripline Power Divider

In this paper, a design of a 64-way $6-18 \mathrm{GHz}$ Wilkinson stripline PWD is proposed, which will be used in phased array antenna systems. The substrate is 4350 B, with a dielectric constant of 3.66, and two different thicknesses of 2.54 mm and 3.38 mm. The PWD is simulated and optimized using HFSS, results show that the 2-way PWD has the values of insertion loss $\geqslant-3.8 \mathrm{~dB}$, return loss $\leqslant-15 \mathrm{~dB}$ and the isolation $\leqslant-$ 15 dB. Meanwhile, the 64 -way PWD has the values of insertion loss $\geqslant-3.8 \mathrm{~dB}$, return loss $\leqslant-15 \mathrm{~dB}$ and the isolation $\leqslant-15 \mathrm{~dB}$.
