Correct Answer - Option 4 : 12-18 GHz
Concept:
- The microwave spectrum is usually defined as a range of frequencies ranging from 1 GHz to over 300 GHz.
- This range has been divided into a number of frequency bands, each represented by a letter.
Explanation:
The commonly used microwave frequency spectrum is as shown:
|
BAND
|
FREQUENCY RANGE (GHz)
|
|
L-Band
|
1 to 2 GHz
|
|
S-Band
|
2 to 4 GHz
|
|
C-Band
|
4 to 8 GHz
|
|
X-Band
|
8 to 12 GHz
|
|
Ku-Band
|
12 to 18 GHz
|
|
K-Band
|
18 to 26.5 GHz
|
|
Ka-Band
|
26.5 to 40 GHz
|
From the above table, it is clear that the Ku band represents the frequency range of 12 to 18 GHz
