Expression for aperture efficiency in terms of physical aperture Ae and effective aperture Aem is ____(a) \(\frac{A_e}{A_{em}}\)(b) \(\frac{A_{em}}{A_e}\)(c) \(\frac{A_e+A_{em}}{A_e-A_{em}}\)(d) \(\frac{A_e-A_{em}}{A_e+A_{em}}\)This question was addressed to me in an interview for internship.The query is from Effective Aperture topic in division Antenna Parameters of Antennas |
|
Answer» CORRECT option is (B) \(\FRAC{A_{EM}}{A_e}\) The explanation is: The aperture efficiency is defined as the ratio of effective aperture to physical aperture of antenna. So aperture efficiency \(\eta=\frac{A_{em}}{A_e}.\) |
