Question
Antenna manufacturer has decided to modify the antenna but with three times the effective aperture area of the previous antenna and keeping wavelength constant. The gain of the modified antenna will be ________Select one:a. 9 times the gain of original antennab. same as the gain of original antennac. three times the gain of the original antennad. twice the gain of original antenna
Solution
To determine the gain of the modified antenna, we need to understand the relationship between effective aperture area and gain.
The gain of an antenna is directly proportional to its effective aperture area. This means that if we increase the effective aperture area of the antenna, the gain will also increase.
In this case, the antenna manufacturer has decided to modify the antenna by increasing its effective aperture area three times while keeping the wavelength constant. Therefore, the gain of the modified antenna will be three times the gain of the original antenna.
So, the correct answer is option c. three times the gain of the original antenna.
