LoRa uses license-free sub-gigahertz radio frequency bands like 433 MHz, 868 MHz (Europe), 915 MHz (Australia and North America) and 923 MHz (Asia). LoRa enables long-range transmissions (more than 10 km in rural areas) with low power consumption. Cowin provides various kinds of products that are different in frequency antenna length such as high frequency radio antenna and low frequency antenna.

FAQs of Frequency Antenna

Q Why is 315MHZ/433MHZ/470MHZ/510MHz PCB antenna low efficiency? A

They belong to low frequency, generally PCB antenna is not used, commonly it used threaded pipe antenna, low frequency directly limited the application of PCB plane antenna.

Q How can the antenna make the receiving distance reach 3 meters when RFID frequency is 862-928mhz ? A

Which type do 315MHZ/433MHZ/470MHZ/510MHZ antenna has?

• End transmitting antenna: such as helical antenna, whip antenna, telescopic antenna. It has an omnidirectional radiation lobe with low gain.

• Loop antenna: Ring antenna and double ring antenna can be designed circular polarization to improve the performance of reading complex placement tags.

• Dipole antenna: Doublet antenna and folded dipole antenna have an about 300 ohm impedance, need a balanced match, It's a standard gain antenna.

D. Microstrip antenna: Torch shape, circular shape, line waveform, slit shape, small volume, thin, suitable for small equipment.The array antenna can achieve high gain.

Applications of Frequency Antenna

LoRa technology has many kinds of application, such as air pollution monitoring, agriculture processing, animal tracking, fire detection, fleet tracking, home security, indoor air quality, industrial temperature monitoring.
