Title: Difference between Helix Antenna and Patch Antenna


1
  • Difference between Helix Antenna and Patch
    Antenna
  • Nowadays, the demand for GPS applications is
    growing all over the world. Helix and Patch
    antennas are widely used in several GPS
    applications. To understand the working of these
    2 antennas, it is necessary to know the meaning
    of both these antennas in detail. We will also
    talk about the benefits of Helix Antenna and the
    differences between these antennas to know the
    better antenna.
  • What is a Helix Antenna?
  • A helix antenna is a type of antenna that is
    developed with or without any ground
  • plane. It emits an omnidirectional radiation
    pattern. This antenna can even work without any
    ground planes. However, the ground plane will
    give better performance in an antenna.
  • If you want to use the ground plane in an
    antenna, it should be placed at a minimum
    distance from the radiation part of the antenna.
    You can use a helix antenna in the internal or
    external part of the space. Helix antennas have
    the features of a zapper and vertical antenna.
    Moreover, the helix antennas can receive signals
    at an angle of 360 degrees.
  • Benefits of Helix Antenna
  • After discussing the meaning of a helix antenna,
    let us now discuss the benefits of this antenna.
    Helix antennas give various benefits such as
  • Used with or without ground plane
  • Helix antennas can be used with or without ground
    planes. They perform better
  • than other types of antennas when you use the
    ground plane. You can use this antenna in a
    variety of GPS applications with the help of a
    ground plane.
  • Suitable for external or internal use of antenna
  • One of the major benefits of a Quadrifilar Helix
    Antenna is that it can be used in
  • the internal and external parts of the devices.

  • Gives higher gain
  • Helix antennas give higher gain than patch
    antennas in the device. As a result, the
  • device works better with helix antennas. You can
    use helix antennas for both VHF and UHF bands.
    They have wide bandwidth and give higher
    directivity than other antennas.
  • Simple design
  • Helix antennas have a simpler design than other
    kinds of antennas. It is easy to
  • design this antenna by using a few components.
    This antenna can give circular polarization as
    well.
  • What is a Patch Antenna?
  • Patch antenna is used in many applications due to
    durability and simple manufacturing. This
    antenna is very easy to design just like helix
    antennas. Patch antennas can be in any shape
    such as long, square, and round.
  • These antennas give high gain when you install
    them on the top side of a ground plane. The most
    popular kind of patch antenna is the ceramic
    type. It has dimensions of various ranges. Patch
    antennas with small ground planes have a
    back-lobe in the radiation pattern.
  • While using the patch antenna, you must look at a
    few important things. The components of this
    antenna should not be mounted near the patch.
    Apart from that, you must also keep a minimum
    distance between antennas and devices. Signal
    line paths should not be used under or near the
    patch antennas.
  • Benefits of Patch Antenna
  • Now, let us discuss the benefits of a patch
    antenna in this section. The major benefits of
    patch antennas are
  • Patch antennas work better than traditional
    antennas which are not feasible.
  • These antennas work at microwave frequencies
    whereas a traditional antenna does not work.
  • It is widely used in many small devices.
  • You can integrate patch antennas with MMIC or
    MICs.

  • Patch antennas are lightweight as well as
    comfortable to use because of their small size.
  • They can support dual, triple, and other
    frequency bands.
  • These antennas will support both linear and
    circular polarization kinds.
  • Patch antennas work better when you mount them on
    the rigid surface of any device.
  • Difference between Helix Antenna and Patch
    Antenna
  • This section explains the differences between
    helix antennas and patch antennas in detail.
  • Use
  • Helix antennas can be used both in the internal
    and external parts of the device.
  • On the other hand, the patch antennas are used on
    the external part of the devices.
  • Gain
  • Helix antennas give a higher gain than patch
    antennas. On the other hand, the
  • patch antennas give a lower gain in any device.
    Patch antennas are very easy to fabricate on
    printed circuit board whereas helix antennas are
    not very simple to fabricate on the circuit
    board because of their small size.
  • Sensitivity
  • Helix antennas show lower sensitivity than other
    kinds of antennas. They cannot
  • detect weak signals from certain radio frequency
    sources. If you want a better sensitivity, use
    patch antennas in the device. They are capable of
    detecting signals from certain sources.

  • Cost
  • Helix antennas are costlier than patch antennas.
    On the other hand, you will get
  • patch antennas at an affordable rate in the
    market. Helix antennas are widely used in
    multiple GPS applications whereas patch antennas
    are generally used in many portable wireless
    applications.
  • Construction
  • It is simple to build a helix antenna for
    engineers whereas patch antennas are difficult
    to build. Helix antennas have a simple design and
    construction. On the
  • other hand, patch antennas have a complex
    structure and design.
  • Final words
  • These are the major differences between helix
    antennas and patch antennas with their benefits.
