A certain cellular telephone antenna has an input impedance at f=1.0 GHz modeled by a shunt R-C combination, with R=200Ω and C=2.0pF. Because of manufacturing restrictions, you can only work with microstrip, and cannot use vias or wrap-around grounds, i.e. all your stubs must be open-circuited. Design a matching network that consists of balanced stubs of either 1/8 or 3/8 wavelength (choose the shortest length that will work) and a quarter-wave transformer. Sketch the microstrip network, and label the lengths and characteristic impedances of the lines. You do not need a Smith chart to do this. Your sketch should depict the equivalent source on the left and antenna (load) network on the right, with the matching network in between.
