1The Beginners Guide to How an Antenna Works
The antenna is one of the most important tools
that simplify communication in our daily life.
We can send and receive messages by using a
powerful antenna. It is also used in TV
broadcasting and radio stations. Apart from
that, the antenna also helps us to talk on
telephones and mobile phones. Many of us do not
have a clear idea of what an antenna is. In this
blog, we will discuss the full guide on how an
antenna works with its types and benefits. How
does an antenna work? Before we discuss the
working process of a UHF Antenna or any other
kind of antenna, we need to understand the basics
of an antenna. Apart
2- from that, we must also understand how radio
waves travel and make communication better on
telephones and mobile phones. Here is the list
of some basic concepts that you can relate to
antennal - Receivers and Transmitters
- Radio communication improves with the use of
transmitters and - receivers. A transmitter sends the signals to the
receiver. A receiver takes the signals and
presents a message in a proper form. - Both transmitters and receivers include various
parts including an antenna. A receiver is an
antenna that helps to receive car radio or
satellite Television. Different antennas have
different shapes and sizes. The size and shape
of an antenna depend on the purpose of the sender
and the distance that the signals have to
travel. - Process of transmission
- Transmission is an important part of the antenna
that you must understand. Transmitters can send
signals only when the antenna - sends an electrical current. This current
generates a magnetic field that helps in the
transmission of signals. The antenna sends
signals according to its frequency or amplitude
modulation. - Frequency modulation and amplitude modulation are
common ways by which data is packed in radio
waves. They are common ways in any VHF antenna
to pack information. - Signals are modulated to contain mono audio
information, text information pilot tone, and
AM-suppressed carrier information. - Process of reception
- Modulated signals are sent by air and the antenna
receives these signals. Carrier signals are
those signals that contain information. These
3signals are modulated and sent through the air
with certain information. These carrier signals
need to be demodulated while sending them to the
receiver. In other term, the signal is decreased
to the pertinent information before sending it
to the receiver. Finally, this information is
transferred to any audio system or speaker
system. These signals will be digitized when
they are sent to video or other media
devices. How do waves travel? Radio waves can
travel in several waves via air. Some radio waves
travel straight from the transmitter to the
receiver. This process is known as the line of
sight. Those waves that travel to transmit phone
calls work in the line of sight trend. This
trend was removed during the 1960s when
fiber-optic cables were used to transmit phone
calls. These phone calls encode data into a beam
of light that is sent via a glass pipe. Ground
wave signals utilize the space between the earth
and the earths ionosphere to carry out
transmissions. These waves can travel a long
distance when you use them at a low frequency.
Many signals depend on ground wave transmission
because many waves experience interruption from
the lights effect on the D section of the
ionosphere. How does Ionosphere affect the
working of signals? The ionosphere is the layer
of the earth that is electrically charged.
It affects the working of radio signals to a
large extent. This layer contains many free
electrons that help to send and receive messages
all over the world. The ionosphere method was
widely used all over the globe
4- before the invention of satellites. It was also
used for broadcasting before the invention of
satellites. - Different kinds of Antennas and their features
- Antennas come in different types with different fe
atures. Every antenna is used for a specific
purpose. Here is the list of different kinds - of antennas with features
- Log periodic antennas
- The first kind of antenna is a log periodic
Dipole Antenna. It includes - antennas such as military log periodic Dipole
Antenna, Bow tie antennas, and log-periodic
antennas. These antennas are widely used to
transmit signals in broadcasting stations. It is
a type of directional antenna developed to work
over several frequencies. - Wire Antennas
- Some of the most popular wire antennas include
Dipole Antenna, a loop antenna, a short dipole
antenna, and a monopole antenna. It also - includes a military coaxial Dipole Antenna. Wire
antennas such as high - gain Dipole Antenna are a very common kind of
wire antenna used in aircraft, ships, vehicles,
and buildings. - Wire antennas come in different sizes and shapes.
Military Dipole Antenna is used in many
vehicles. - Aperture Antennas
- The next kind of antenna is an Aperture antenna.
These antennas are further divided into Slot
antennas and horn antennas. These types of - antennas come with an opening in the surface to
emit various radio waves.
5- Microstrip antennas
- Microstrip antennas include a rectangular
microstrip patch antenna and - a Quarter-wave patch antenna. These antennas are
widely used in space crafts, radars, wireless
communication systems, and missiles. - Travelling wave antennas
- Marine Dual Band Yagi Antenna is a kind of
traveling wave antenna. - Apart from that, the traveling wave antennas also
include helical wire antennas, long wire
antennae, and spiral antennae. They are used in
radio and telecommunication structures. - Array Antennas
- The next kind of antenna is the Array antenna. It
is further divided into - linear array antenna, phased array antenna, and
two-element array antenna. - Final words
- This is a perfect beginners guide on the working
of antennae and types - of antennas. You can find the best antenna
manufacturer from the official site or Google
search engine. - This guide will help you to understand the
working of the antenna. It will also give you an
idea of different kinds of antennas and their
uses. The working of the antenna is important to
find its basic structure and other details.
