Difference Between Helix Antenna and Patch
Antenna
Antennas are crucial equipment that helps in
wireless communications, and navigation. The two
most demanding antennas are the helix antenna and
the patch antenna. These are used for similar
purposes, but they have many differences that
make them suitable for different
applications. You can understand the difference
between helix and patch antenna by going through
this helpful guide. This detailed guide will help
you to make the right decision about which
antenna is best for you. Lets get
started! Helix Antenna A helix antenna is a
versatile antenna that establishes communication
in many devices, including drones, automated
vehicles, etc. They feature circular
polarization and high gain capability, which
makes them the best option for many outdoor and
indoor situations. Helix antennas are known for
their small, straightforward design that does not
need any special setup. That indicates that you
can use it in many situations to gain better
experience. The Quadrifilar helix antenna is made
of a helical shape with four wires. It sends out
signals with a specific circular pattern that
increases its performance even in rotating
devices. You can implement this type of antenna
in your system if you want to prioritize a
low-profile antenna with strong signal
strength. Patch Antenna A patch antenna is a
well-known antenna that is mainly used in GPS,
satellite communication, and wireless networking
systems. These antennas are small in size and
cheap to make. It is used in applications where
traditional equipment doesnt work.

Patch antennas are made up of their unique
design. It consists of a flat piece of metal on
a plastic base with a metal plate underneath. In
this structure, the flat piece works to
establish communication. The metal plate gives
better signal reception. This design makes it a
suitable option to integrate with electronic
devices such as smartphones and GPS
receivers. Patch antennas come in small sizes,
but they can make reliable signal reception and
transmission. That makes them one of the popular
choices for many applications. Differences
Between Helix and Patch Antennas Both antennas
are useful in modern communication systems. They
are used for establishing reliable transmission
of singles over long distances. But they also
have many differences in their design and
performance. Here you can explore these crucial
points. That will help you to make the difference
between helix and patch antennas. Geometry The
helix antenna comes with a three-dimensional
spiral structure. This special design helps it
to offer circular polarization. That is the
reason it is often employed in applications such
as satellite communications and space
missions. On the other hand, the patch antenna is
two-dimensional. It comes with a small size and
you can easily integrate them in many outdoor and
indoor situations. These antennas are commonly
used in applications like mobile phones, GPS
devices, etc. Radiation Pattern Helix antennas
are omnidirectional antennas. You can use it to
send and receive signals equally in all
directions. These are suitable for applications
where 360-degree coverage is paramount, such as
satellite communications.

On the other hand, patch antennas are directional
antennas. They provide the ability to establish
communication in specific directions. You can use
it for point-to-point communication, such as
WiFi routers, TV broadcasting, etc. Based on
radiation patterns, helix antennas are a better
option to provide broad coverage, while patch
antennas are better for targeted and point-to-
point communications. Circular vs. Linear
Polarization Helix antennas usually offer
circular polarization. That means it rotates the
signal in a spiral pattern. Integrating this
wireless solution into your system reduces the
interference of signals. This is the reason we
often see these antennas in satellite
communications and mobile applications. They
feature circular polarization that ensures
consistent signal quality in every situation. On
the other hand, patch antennas work in linear
polarization and align the signal in a straight
line. They help make the seamless transmission of
signals when both the transmitter and receiver
are aligned. Size and Profile Helix antennas are
larger and bulkier than patch antennas. They have
a three- dimensional structure, which makes them
suitable for satellite communications. On the
other hand, patch antennas possess a small and
flat size. You can integrate this antenna if you
want an antenna that covers limited space. Patch
antennas are ideal for devices with limited
space. They are low- profile antennas and are
used to integrate into electronic devices. You
can see patch antennas are incorporated in
smartphones, GPS receivers, and wireless
routers. Ground Plane Requirement Helix antennas
often need a ground plane to work their best.
This ground plane is nothing but a flat surface
that helps improve the performance of sending and
receiving signals. If any antennas need a ground
plane, that means your installation process can
be more complicated and space-consuming. On the
4
other hand, patch antennas come with a compact
and straightforward design. These antennas can
function well without requiring any ground
plane. Frequency Band Helix antennas are
versatile wireless solutions. They support a wide
range of frequency bands. Usually, you can use
them to communicate with frequencies ranging
from around 30 MHz to 3 GHz. They are also good
at making communication possible in VHF and UHF
radio frequencies. That makes them flexible and
suitable for various applications. In contrast,
patch antennas are usually not as flexible as a
helix. These work best in the frequency range of
2 to 50 GHz. That means you can use them to make
communication for targeted applications. Conclus
ion Both helix antennas and patch antennas are
crucial for modern wireless communication. These
antennas differ greatly in terms of their
radiation pattern and frequency band. As we see,
helix antennas are suitable for a situation if
you want precise versatility and flexibility in
your wireless solutions. On the other hand, for
low power and less space, you can turn to patch
antennas. However, it is important that, before
choosing any of the equipment, you consider your
requirements and needs. We hope this guide
encourages you to explore more about these two
antennas, as you may have overlooked the
differences between them.
