For example, a radio station might broadcast music as an FM signal, which is a type of radio wave in the EM spectrum. The station's transmitter sends the music to the antenna in the form of electric current at the desired frequency. The antenna converts the electric current to radio wave...
Another one of the most common antenna designs associated with television reception is Yagi-Uda antennas, also known as directional or beam antennas. These usually consist of an array of dipole shafts and reflectors that help to focus the signal for better reception. Most are mounted on or ...
I always think “why did you even bring up the subject if you’re not going to explain what it is?” Luckily for you, I know something about antenna feed horns. Feed horns are used a lot in satellite dish and antenna design, as a bridge between the transceiver and the reflector. ...
An antenna element is any part of an antenna that is actively used for the reception or transmission of signals. Common types of...
As the vehicle moves, the vertical antenna at the base station will not need to re-orientate their antenna. So too on the vehicle where it will be changing its direction, the all around radiation and reception is essential. Vertically polarised radiation: Having a vertical element, or elements...
the feed structures of this low-profile antenna are simpler. Compared to a reflector antenna, the height of the VICTS antenna is only 10 cm for the Ku-band which makes it a prospect for communications on the move. It can be mounted on the surface of an aircraft or other vehicle withou...
A Yagi antenna or a Yagi-Uda antenna, is a directional antenna that radiates signals in one main direction. It consists of a long transmission line with a single driven element consisting of two rods connected on either side of the transmission line. It also consists of a single reflector on...

aDon' t be afraid to admit that you are less than perfect. It is this fragile thread that binds us each together. Your name is such ordinary but it affects my mood all roun 不要害怕承认您比完善是。 它是一起束缚我们中的每一的这条易碎的螺纹。 您的名字是这样平凡,但它影响我的心情所有...
(encoding, forward error correction, power amplifier, antenna) as well as the complementary receiver side (antenna, low noise amplifier, receiver, decoding, error correction). The channel itself — the RF medium — has, however, generally been considered as an “as-is” or “given” element ...
