Antenna Design and Testing Services
In the Antenna Design and Testing Laboratory facilities, tests related to the functional parameters of the antennas can be performed, such as: radiation properties, S-parameters, power, among others. In addition, the available Anechoic Chambers are also suitable for acoustic tests. In terms of development, design and construction of antennas are available options.
LaMA has 3 Anechoic Chambers of different sizes, equipped with high quality measuring instruments, which allow performing different types of tests according to the requirements requested by the customers. The coordinate systems that can be used are Planar, Cylindrical and Spherical.
In addition, it is able to perform tests at different temperatures by inserting the antennas inside the Thermal Chambers available in the laboratory. In particular, for cylindrical coordinates and small or medium-sized antennas (dimensions up to 1.5 m x 0.5 m x 0.5 m), the thermal measurement range is from -100°C to 100°C; while in the planar system and for large antennas (up to 1.5 m x 3.5 m x 1 m), the same is from -60°C to 70°C.
In the case of Power Handling tests, the available frequency range is between 800 MHz and 3 GHz.
Antenna designs and analysis are performed with commercial software using finite element methods applied to electromagnetic structures.

Features
- Air treatment system that guarantees an environment with a quantity of 100,000 particles per cubic foot of air (Standard: Fed-std-209E / ISO14644), and with controlled temperature and humidity (Temperature: 22°C ± 3°C, Relative Humidity: 55% ± 10%), complying with the ISO 8 (ISO14644) standard of the European Cooperation for Space Standardization (ECSS).
- Laboratory consisting of 3 ISO 8 class anechoic chambers, designed to absorb all the reflections produced by electromagnetic waves on any of the surfaces (floor, ceiling and side walls). At the same time, they are isolated from the outside, which protects them from any source of external influence. The combination of these two factors means that the rooms emulate space-like conditions.
