New flat phased array antenna from QEST


QEST Quantenelektronische Systeme has unveiled a new flat phased array antenna for aeronautical connectivity.

The product features electronic beam steering rather than conventional mechanical positioning, which QEST says results in an antenna system that is smaller, flatter and lighter.

In addition, the antenna and aerodynamic cover (radome) are integrated into a single compact device, making a “significant” cost reduction achievable, the company says. The phased array antennas will be available for both Ku-band and Ka-band applications.

“Ongoing simulations and initial tests of our novel phased array technology are producing very good results,” said Dr Jörg Oppenländer, CTO at QEST. “We are planning to finalize a first functional demonstration unit by the end of 2016. Series production should start in 2018.”

With its diversified antenna portfolio, QEST enables global broadband connectivity, supporting high-speed internet and direct TV reception. “The required satellite bandwidth represents a large portion of the operating expenses of connectivity,” said Michael Stobinski, CCO at QEST. “The more efficient the antenna system is in utilizing this precious bandwidth, the more economical the overall operation of connectivity services for airlines.”
