In this insightful video by Mouser Electronics, we delve into the world of antennas, the passive metal structures designed to capture or emit electromagnetic waves. Essential components of wireless communication technology, antennas enable electronic devices to transmit and receive signals wirelessly and are found in a multitude of products, including automotive, cell phones, radar systems, and satellite communications.
The video explains how antennas work, likening the propagation of radio waves to ripples on water. When an electrical signal is applied to the antenna, it creates a changing electromagnetic field around it, propagating through space as an electromagnetic wave. Similarly, when the antenna encounters an electromagnetic wave, it induces an electrical signal which can be detected and amplified by electronic circuits.
The design of an antenna determines its efficiency, radiation pattern, and ability to transmit and receive signals in different directions and frequencies. Matching the antenna size and shape to the wavelength of radio waves is crucial for optimal performance.
The video also highlights the range of high-efficiency and reliable antennas from TE Connectivity and KYOCERA AVX, available at Mouser Electronics.
