Application: Double stub matching. An antenna has an impedance of 68+j10Ω. The antenna needs to be connected to a 75 n line. Because the antenna goes on a mast, the design engineer decided to fabricate a matching section as shown in Figure 15.38. The matching section is then hoisted and connected to the antenna during installation. At the required frequency, the section is 0.3λ and two stubs are made of the same line. Calculate the lengths of the stubs, if the antenna is connected at A-A.
