80 GHz antennas are a key element of modern communications systems, used in applications requiring very high data throughput over short and medium distances. The 80 GHz frequency, part of the E-band (70-80 GHz), offers unique advantages that make it increasingly popular over lower frequencies.

Applications for 80 GHz Antennas:

  • Last Mile/First Mile Links: Ideal for quickly delivering internet to buildings where traditional cables are difficult or expensive to install
  • Mobile Backhaul: Enables the transmission of large amounts of data to and from 5G and 4G LTE base stations
  • Campus and Enterprise Networks: Provides fast and reliable connectivity between buildings within a campus or office complex
  • City Surveillance and CCTV Systems: Enables the transmission of high-resolution video streams from city cameras
  • Redundant and failover networks: These can serve as backup links in the event of a primary connection failure
  • Point-to-Point links: A classic application for building high-speed radio bridges


Advantages of 80 GHz Antennas:
 

  • Very High Throughput: The 80 GHz band offers wide channels (e.g., 250 MHz, 500 MHz, 750 MHz), enabling gigabit data rates (e.g., 1 Gbps, 2.5 Gbps, 5 Gbps, and even 10 Gbps and more)
  • Small Antenna Size: The short wavelength in the 80 GHz band allows for the design of much smaller antennas while maintaining high gain
  • High Interference Resistance: Due to its high frequency and strong signal attenuation by rain and snow (which is a disadvantage over long distances), the 80 GHz band is relatively less susceptible to interference from other radio devices
  • High Beam Directionality: 80 GHz antennas feature a very narrow beam, minimizing interference with neighboring links and increasing transmission security
  • Licensing-Free (in some countries/bands): In many regions The 80 GHz band (E-band) is available worldwide, including in Poland, without the need to obtain individual licenses, significantly simplifying and accelerating system deployment
  • Fast Return on Investment (ROI): Thanks to high throughput and rapid deployment, investing in 80 GHz technologies can yield quick benefits, especially in the context of growing demand for the band


What to Consider When Choosing an 80 GHz Antenna:

  • Antenna Type (Parabolic, Flat)
  1. Parabolic antennas: Offer the highest gain and the best parameters (VSWR, polarization isolation), ideal for longer distances and demanding applications. Available in various diameters (e.g., 30 cm, 60 cm, 90 cm)
  2. Patch antennas: Smaller, more discreet, and easier to install, but with lower gain. Suitable for very short distances and locations where aesthetics are a priority
  • Antenna Diameter (for parabolic antennas): The larger the diameter, the higher the antenna gain and the longer the transmission range. The choice depends on the distance between the points and the required link availability (e.g., 99.999%)
  • Antenna Gain (dBi): A key parameter determining the antenna's ability to concentrate signal power. Higher gain means longer range and/or greater resistance to attenuation
  • Polarization: Most 80 GHz systems use dual polarization (horizontal and vertical) to increase throughput through channel aggregation. Ensure the antenna supports the required polarization
  • VSWR (Return Loss): The lower the VSWR (closer to 1:1), the better the antenna matches the radio path and the less signal loss
  • Radiation Pattern (Beamwidth): A narrow beam is desirable to minimize interference. Check the Half Power Bandwidth (HPBW) angle
  • Weather Resistance: Outdoor antennas must be resistant to rain, snow, wind, UV radiation, and extreme temperatures. An IP rating (e.g., IP67) is important
  • Ease of Mounting and Adjustment: Mounting systems should be robust and allow for precise antenna alignment, which is crucial in the 80 GHz band due to the narrow beam
  • Compatibility with Radio Devices: Ensure the antenna is compatible with the selected 80 GHz radio links (e.g., waveguide interface, connector type)
