2. In the circuit shown below, the operating frequency for the transmit antenna is 300 MHz. At this frequency, we can represent the transmission line and antenna with a resistive load RL. This resistance accounts for radiated electromagnetic wave. The variable capacitor and inductor shown were tuned to achieve an impedance matching condition, i.e. where ZL is the impedance of the transmission line-antenna assembly and Zr is the Thévenin equivalent impedance of the driver circuit, including R., C and L....
