Antennas
GPS/GNSS Antenna
ATAT1A
GPS/GNSS antennas are devices that receive signals from positioning system satellites to determine the precise location of the receiver.
What is the purpose of GPS/GNSS antennas?
GPS (Global Positioning System) or GNSS (Global Navigation Satellite System) Antennas for positioning system allow tracking and location devices to access positioning satellites, capturing the signals transmitted from space, which are transferred to a processing unit will determine the location of receivers, such as mobile phones, tracking devices, in-vehicle navigation systems, IoT systems.
What type of GPS/GNSS antennas exist?
Normally GPS/GNSS antennas have a compact design, and can be internal within the receiving devices or external.
What are the most important parameters in GPS/GNSS antennas?
Orientation: They are usually omnidirectional, that is, they receive signals emitted from any position and thus establish the precise location of the location.
Gain: Determines the ability to amplify weak signals emitted by global positioning satellites.
Impedance: Represents the amount of Ohms with which it opposes the flow of current. Usually the impedance with which antennas and devices are manufactured is 50 Ω.
Resistance to interference: Determines the minimization of interference from other nearby electromagnetic devices.
Radiation pattern: GPS/GNSS antennas are typically omnidirectional, meaning they can receive signals from any direction, making it easy to determine precise location.
