Título: LENS ANTENNAS - Part 1: Introduction.


Descripción automática: In this video, the presenter, who is affiliated with the Relations of Technology, delivers a lecture on lens antennas. The lecture is structured into different parts, starting with the basics of lens antennas and their importance. It then progresses to discussing various types of lens antennas, such as spherical and aspherical lenses, highlighting their main limitations, including aberrations and reflections.

Additionally, the lecture touches on the history of lens antennas in optical applications and their adaptation to the microwave frequency band, explaining their past limitations, such as size and cost, which restricted their use. With the advent of higher frequency applications, lens antennas have gained renewed interest in the research community for potential use in telecommunications systems, RFID, and radar imaging.

The presenter explains that lens antennas can be implemented in two main types of systems: imaging systems, which create an image of an object, and antenna systems, which focus electromagnetic waves for reception or transmission. The presenter then delves into the theory behind lens antennas, discussing the principles of refraction, reflection, and the differences in phase velocity due to the refractive index.

Towards the end of the video, the presenter introduces formulas for calculating the amplitude of transmitted and reflected waves when they pass through different media. The video concludes with a summary of the theoretical aspects of lens antennas and their applications.
