Omega2 Antenna

Ka-band OTM electron beam steering ESA antenna, marine, aircraft, vehicle mobile service

The Omega2 ESA in the 17.5GHz ~ 31GHz KA band has a very short wavelength. The short wavelength requires high precision in the design and manufacture of antenna elements.

Even slight manufacturing errors can significantly impact performance.

The Omega2 antenna is a phased array antenna capable of providing stable service in a compact structure.


[Reasons for the Challenges in Developing KA Band ESA Antennas ]

  • As frequency increases, signal path loss becomes greater. To compensate for this, transmission and reception equipment with high power and sensitivity are required, which increases technical complexity and costs.
  • High frequencies require high-performance materials with low conductivity and dielectric losses. These materials are expensive and difficult to process.
  • KA band ESA antennas require fine patterns and precise assembly. This necessitates advanced manufacturing techniques and equipment, and minimizing defects in the production process is crucial.
  • Effective thermal management is required to handle the heat generated during signal processing. Thermal management is vital for maintaining antenna performance and longevity. A sophisticated thermal management system is necessary to effectively dissipate heat at high frequencies.
  • In the KA band, signal processing and beamforming algorithms must be highly sophisticated. This requires high-performance processors and advanced software, increasing development complexity and costs.

Full-Duplex ESA Antenna

Simultaneous Transmission and Reception

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


The simultaneous transmission and reception capability allows for more data to be processed faster. This is particularly advantageous for high-capacity data communications such as high-speed Internet, real-time streaming, and high-resolution video transmission.


Full-duplex ESA antennas are highly compatible with next-generation communications technologies such as 5G and 6G. These technologies require high-speed data transmission and low latency, making full-duplex mode essential.


Excellent Alpha OTM antenna performance with fast beam switching speed

Pol Switching Time : <0.5ms

Satellite Switching Time : ≤0.3ms

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


Signal interference is a major problem in satellite communications. Fast beam switching speed allows signals from specific users to be quickly switched to another direction to minimize interference. This allows for cleaner and more stable communication signals.


Fast beam switching speed 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 using traditional mechanical motors



Without mechanical motors, ESA antennas have no moving parts, avoiding mechanical problems such as wear, failure, and maintenance. This greatly improves

 the reliability and lifespan of the antenna.


Electronic beam steering is much faster than mechanical motors. This is a significant advantage in multi-satellite

tracking, etc. The fast response speed minimizes communication delays and maximizes efficiency.


Electronic control allows for very precise beam steering. This allows for precise control of the directionality and strength of the signal, minimizing interference and improving communication quality.
