June 1, 2022 By WatElectronics

This article lists 40 Yagi Uda Antenna MCQs for engineering students. All the Yagi Uda 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 the Yagi Uda Antenna.

An antenna is an electro-mechanical device designed for digital or electromagnetic communication purposes. They are classified into multiple types such as log periodic type antennas, wire type antennas, traveling type wave antennas, and more.

An antenna designed with a narrow band-based functionality is a yagi antenna, a Yagi Uda antenna. The scientists who discovered YU antennae are Hidetsugu Yagi and Shintaro Uda. The components of the YU antenna include transmitters, receivers, and passive-type radiators.

The advantages of the Yagi antenna include light weight, simple construction, and less cost. The disadvantage of Yagi-antenna is noisy and experiences atmospheric effects.

The applications of the Yagi antenna include radar antennas, television antennas, and point-to-point fixed communication.
