Introduction to Transmission Line – 1 – 1

1. A system of conductors used to convey electric power or signal  between two or more points :

(a) Channels
(b) Optical cables
(c) Transmission lines
(d) Waveguides

ANSWER

EXPLANATION

2. These conductors are uniformly spaced by insulators. They have low losses at low and medium frequencies and are economical to construct and maintained :

(a) Coaxial cables
(b) Open-wire transmission lines
(c) Optical cables
(d) Waveguides

ANSWER

EXPLANATION

3. To prevent radiation losses and interference from external sources, the inner conductor of this transmission line is completely enclosed with a metal sheath or braid :

(a) Coaxial cables
(b) Open-wire transmission line
(c) Optical cables
(d) Waveguides

ANSWER

EXPLANATION

4. This transmission line is used in microwave circuit. It consists of a narrow, flat conductor sandwiched between dielectric boards whose outside surfaces are coated with conductor :

(a) Stripline
(b) Microstrip
(c) Waveguide
(d) Coax

ANSWER

EXPLANATION

5. Is a narrow, flat conductor on a single dielectric board whose opposite face is metallized, much like an ordinary printed-circuit board. It is also used in microwave circuits :

(a) Stripline
(b) Microstrip
(c) Waveguide
(d) Coax
