1.	Normal mode of radiation is limited in use because _____(a) it has narrow bandwidth and dependency on small dimensions of the antenna compared to wavelength(b) it has broad bandwidth and independent of antenna dimensions(c) it has narrow bandwidth and is independent of antenna dimensions(d) it has broad bandwidth and dependency on large dimensions of the antenna compared to wavelengthI got this question in an online interview.The question is from Frequency Independent Antenna topic in section Frequency Independent Antenna of Antennas
Answer» Correct choice is (a) it has narrow BANDWIDTH and dependency on small dimensions of the antenna compared to wavelength To elaborate: The normal MODE of RADIATION depends on the size of the antenna. Its critical dependency on dimensions of antenna which has to be less than the wavelength is difficult and so it causes for narrow bandwidth and LOW radiation efficiency.
