A $75$ ohm line feeds a load which may exhibit two different normalised admittance at different times based on reasons out of the scope of this question. The two normalized admittance is $0\mathrm{.}3+$j$0\mathrm{.}2$ and $0\mathrm{.}4+$j $0\mathrm{.}7.$ You are asked to design a stub matching solution which is able to match both these admittances without changing the positions of the stub$($s$).$ The user will have the flexibility to change the length of the stub$($s$)$ to arrive at a match when the admittance switches. You have to suggest to the user the lengths of the stub$($s$),$ which will give good matching for each of the above two cases. The constraints given to you by the user is that when the load exhibits an admittance of $0\mathrm{.}3+$j$0\mathrm{.}2,$ the first stub is located at a distance of $0\mathrm{.}13$lambda away from the load. You are free to select a choice of any stub matching technique to arrive at an appropriate solution. The matching should be at a frequency of $1$ GHz$.$ 

Which method would you select and why? 

Draw the APLAC schematic of your solution when the normalised load admittance is $0\mathrm{.}3+$j$0\mathrm{.}2.$ All values must be clearly labelled in your schematic. 

Draw the APLAC schematic of your solution when the normalised load admittance is $0\mathrm{.}4+$j$0\mathrm{.}7.$ All values must be clearly labelled in your schematic.
