Design a $1$:$2$ T$-$junction power divider using CST with the following specifications:

Operational at $1\mathrm{.}4$ GHz

Substrate: ROGERS $4350($loss free$)228\mathrm{.}6$ mm x $304\mathrm{.}8$ mm $($thickness $=1\mathrm{.}4986$mm$)$

Copper lines: Copper $($annealed$)($thickness $=0\mathrm{.}035$mm$)$

Your design should include $/4$ impedance transformers to ensure that all ports have $50$ characteristic impedance.
