Dipole Antenna Question & Answers October 12, 2022 By WatElectronics This article lists 30 Dipole Antenna MCQs for engineering students. All the Dipole Antenna Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Dipole Antenna. Dipole Aerial or antenna are the basic elements of antenna used in radio reception, broadcasting, and so on. It can be used as a part of a complicated array antenna. For Radio communications self it is used or accommodated as a driven or radiating element for the other antenna. A dipole is simple relatively for implementation as well as calculations. Basic dipole antenna designing is easier and it is operated on high frequencies, very high frequencies as well as ultra-high frequencies of the RF spectrum. Yagi-directional antennas being used commonly in television comprised of dipole antennas as the driving element. Not only this many other antennas like Parabolic reflector antennas also make use of this dipole antenna. Dipole the name itself suggests it contains two items or poles. Current tends to flow from the conducting elements present in it. Currents and voltage associated cause electromagnetic waves to radiate outwards from the antenna. 1). How many conduction elements are in a Dipole antenna? One Two Three Four None Hint 2). _________ antennas have center-fed driving element? Dipole Antenna Loop Antenna Monopole Antenna Short-loop Antenna None Hint 3). Which is the simplest among antennas used practically? Dipole Antenna Loop Antenna Monopole Antenna Short-loop Antenna None Hint 4). Feedline on each side to the receiver or a transmitter have a connection with __________? Insulator Conductor Semi-conductor Antenna None Hint 5). What can be used as a resonant antenna? Dipole Antenna Loop Antenna Monopole Antenna Short-loop Antenna None Hint 6). Which dipole has an overall length lesser than ½ λ? Short Dipole Half-wave Dipole Folded Dipole Monopole None Hint 7). __________ separates two sections of a dipole antenna? Insulator Conductor Semi-conductor Antenna None Hint 8). What is the maximum at the dipole antenna center? Voltage Current Temperature Pressure None Hint 9). Where does the source of voltage apply to a Dipole antenna? Right Side Left Side Center a & b None Hint 10). Dipole antenna have _________ maximum at dipole antenna ends? Voltage Current Temperature Pressure None Hint Dipole Antenna MCQs for Exams 11). Dipole antennas pattern of radiation is ________ to antennas axis?

Ratio of Voltage & Current Ratio of Current & Voltage Ratio of Voltage & Temperature Ratio of Current & Temperature None Hint 15). When does the efficiency of dipole antennas can be maximum? Source & Load Impedances are Equal Source & Load Impedances are Different Source & Load Impedances are Distinct Source Impedance Greater Than Load None Hint 16). How much is the resistance of radiation for dipole antennas ideally? 70 Ohms 71 Ohms 72 Ohms 73 Ohms None Hint 17). __________ is referred to as a balance antenna? Dipole Antenna Loop Antenna Monopole Antenna Short-loop Antenna None Hint 18). What is the most commonly used feeder in dipole antennas? Optical Fiber Coaxial Cable Metal Rod Silver Rod None Hint 19). Dipole antennas are ___________? Unidirectional Bi-directional Directional Omnidirectional None Hint 20). Input impedance of dipole antennas is ________? High Low Constant Fixed None Hint Dipole Antenna MCQs for Students 21). How the dipole antenna gain can be increased? Introducing Directors Connecting Multiple Lines Infront of Dipoles Decreasing Directors a & b None Hint 22). Dipole antennas are fed __________?
