INTRODUCTION TO MICROWAVE TRANSMISSION LINE

A transmission line  basically considered as two or more parallel

conductors which is used to connect a __________ to a load.

The transmission line is represented by an equivalent circuit with its electrical properties

characterized by groups of parameters such as

resistance, inductance, capacitance  and ____________

that are distributed uniformly along the line.

A transmission line  has

a characteristic impedance of 70Ω  and

is terminated by  load of 120-j80Ω. 

Determine its reflection coefficient.

• 0.625<40.38⁰

• 0.458<-39.07⁰

• 0.252<-36.42⁰

• 0.545<62.17⁰

The load for the following transmission line  is not the same as the characteristic impedance of the line.

i) Will there be a standing wave generated in the transmission line?

ii) If yes calculate the VSWR and the reflection coefficient

at the load end.

The figure  displays the maximum and minimum amplitudes of the resultant signal which occurs when the reflected wave is in phase and 180 deg out of phase with the input signal, respectively.  Calculate VSWR for the transmission line.
