Prоblem 1A An аntennа with а 50 Ohm input impedance is tо be used in a RF frоnt-end for a transmitter that has a target impedance seen looking toward the antenna of 5 Ohms. Calculate the values for a single open stub matching network needed to match the antenna for a design frequency of 2 GHz. Assume all lines used are of 50 ohm characteristic impedance and find the network that uses minimal electrical line lengths for both the transmission line and open circuited stub used and draw the circuit schematic, including the antenna as a lumped impedance block. Show how the matching solution works on a Smith chart. Clearly label all steps and intermediate calculations. Express your solution in electrical lengths in degrees for each matching network element as follows. E_line ______ degrees E_stub ______ degrees
