The ASTRI Antenna R&D Centre combines both experienced engineering talents with industrial grade measurement facilities and equipment. The engineering team has solid experience in both far-field antenna and near-field RF coil designs. The Centre offers a wide range of antenna/coil design and measurement services from advanced measurement to complete designs, from project inception to final production.

The design team develops antennas for mobile and fixed wireless applications, providing solutions for all applications that require high performance technology. Patented antenna technology and application-driven expertise are used as basis for designing unique customized antennas.

Designing an antenna takes 5-7 days. A single antenna design with a complete measurement report will be delivered as a result. The Centre also provides consultancy and measurement services, which include passive (antenna efficiency, gain) and active (TRP, TIS) measurements, data analysis, reporting and suggestions of antenna/device performance improvement.

Miniaturization: This is currently the driving force in almost all areas of electronics. Therefore, a miniature internal antenna is essential in providing a competitive product. ASTRI Antenna R&D Centre pioneered in providing small antenna designs that can be directly integrated into communication devices.

Better efficiency and gain: Antenna efficiency and gain translate directly into receiver sensitivity and battery lifetime of portable devices. The Centre develops antennas that achieve efficiencies very close to the theoretical limit.

Multi-band: Ubiquitous connectivity is a common requirement for communication systems. The Centre designs antennas with multiple frequency bands allowing inter-operability of different communication systems and standards within a single component.

Cost reduction: The Centre offers competitive technologies and solutions suitable for mass production which requires reduced material and processing costs. When designing an antenna, we need to provide optimum combination of performance and size at a reasonable cost. For this, state-of-the-art commercial simulation tools, a fast prototyping infrastructure, modern measurement and testing facilities are employed.
