Global Konet Omega2 ESA GA450-PAA-52-K Antenna

Omega2 ESA in the 17.5GHz ~ 31GHz KA Band

The Omega2 ESA operates within the 17.5GHz to 31GHz KA band, which features a very short wavelength. This short wavelength demands extremely high precision in the design and manufacturing of antenna elements. Even slight manufacturing errors can significantly impact performance. The Omega2 antenna, a phased array antenna, is capable of providing stable service within a compact structure.

Full-Duplex ESA Antenna for Simultaneous Transmission and Reception

The Omega2 ESA antenna uses full-duplex technology to simultaneously transmit and receive signals, maximizing data throughput. This capability eliminates delays between data transmission and reception, thus increasing bandwidth efficiency in two-way communications.

• High Data Throughput:
  The simultaneous transmission and reception capability allows for faster data processing, which is particularly advantageous for high-capacity data communications such as high-speed Internet, real-time streaming, and high-resolution video transmission.

• Compatibility with Next-Generation Technologies:
  Full-duplex ESA antennas are highly compatible with next-generation communications technologies like 5G and 6G, which require high-speed data transmission and low latency, making full-duplex mode essential.

Alpha OTM Antenna Performance with Fast Beam Switching Speed

• Fast Switching Times:

  • Pol Switching Time: <0.5ms
  • Satellite Switching Time: ≤0.3ms

  Fast beam switching speed enables reliable real-time communication with fast-moving low-Earth orbit satellite users or base stations. This is especially advantageous for communication with moving aircraft, ships, and vehicles.

• Minimized Signal Interference:
  Signal interference is a major issue in satellite communications. Fast beam switching allows signals from specific users to be quickly redirected to another direction, minimizing interference and resulting in cleaner and more stable communication signals.

• Efficient Resource Allocation:
  Fast beam switching enables efficient allocation of network resources. Antennas can quickly switch beams as needed to optimize resources and improve the overall performance of the network.

Electronically Steered Beams Without Traditional Mechanical Motors

• Improved Reliability:
  ESA antennas, which operate without mechanical motors, have no moving parts. This design avoids mechanical issues such as wear, failure, and maintenance, thereby greatly improving the reliability and lifespan of the antenna.

• Speed Advantage:
  Electronic beam steering is significantly faster than mechanical motors, offering a substantial advantage in multi-satellite tracking and other applications. The fast response speed minimizes communication delays and maximizes efficiency.

• Precision Control:
  Electronic control allows for very precise beam steering. This precision enables accurate control of the signal's directionality and strength, minimizing interference and enhancing communication quality.
