Q. |
Antenna’s efficiency is given by the ratio of |
A. | effective aperture to physical aperture |
B. | physical aperture to effective aperture |
C. | signal power to noise power |
D. | losses |
Answer» A. effective aperture to physical aperture | |
Explanation: the larger the antenna aperture the larger is the resulting signal power density in the desired direction. the ratio of effective aperture to physical aperture is the antenna’s efficiency. |
