Contact your instructor regarding equivalent items to ensure that the objective of this experiment is maintained. Introduction The most basic of electrical circuits contains a single resistor connected to the terminals of a battery. This is a complete circuit‚ forming a continuous path between the battery terminals. The resistor is called the load and the battery is the source of emf. We assume that

Double stub impedance matching Impedance matching can be achieved by inserting two stubs at specified locations along transmission line as shown below There are two design parameters for double stub matching: The length of the first stub line Lstub1 The length of the second stub line Lstub2 In the double stub configuration‚ the stubs are inserted at predetermined locations. In this way‚ if the load impedance is changed‚ one simply has to replace the stubs with another set of different

deg. In this case parasitic element is director. Optimum distance between reflector to driven element varies between 0.15-0.25 Lambda. Length of reflector to director decreases in order of about 0.5 Lambda. The input impedance of folded dipole increases in order of n^2 (impedance of dipole). Balanced feed is given to the antenna. If you use a co-axial then BALUN (balanced to unbalanced transformer is used . Application (a)TV reception in VHF Band (30-300 MHz). (b)It is also used in HF‚ VHF‚ UHF
