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 Hint 2). _________ antennas have center-fed driving element? Dipole Antenna Loop Antenna Monopole Antenna Short-loop Antenna Hint 3). Which is the simplest among antennas used practically? Dipole Antenna Loop Antenna Monopole Antenna Short-loop Antenna Hint 4). Feedline on each side to the receiver or a transmitter have a connection with __________? Insulator Conductor Semi-conductor Antenna Hint 5). What can be used as a resonant antenna? Dipole Antenna Loop Antenna Monopole Antenna Short-loop Antenna Hint 6). Which dipole has an overall length lesser than ½ λ? Short Dipole Half-wave Dipole Folded Dipole Monopole Hint 7). __________ separates two sections of a dipole antenna? Insulator Conductor Semi-conductor Antenna Hint 8). What is the maximum at the dipole antenna center? Voltage Current Temperature Pressure Hint 9). Where does the source of voltage apply to a Dipole antenna? Right Side Left Side Center a & b Hint 10). Dipole antenna have _________ maximum at dipole antenna ends?
