The increasing proliferation of drones - including their use in civil and commercial context - has made it necessary to adopt effective countermeasures against improper or malicious operations. Counter-Unmanned Aircraft Systems (C-UAS) now represent a strategic component for the protection of critical infrastructures, tactical assets, sensistive areas, and complex operational scenarios.

ElettroMagnetic Services Srl supports the development of C-UAS platforms through the design and production of custom professional antennas, optimized for jamming, direction finding (DF), spoofing, and high-performance multiband integrated systems. 

Application Areas

C-UAS systems are employed across a wide range of civil and military contexts. Below are some examples.

Civil contexts:

- Airport security and urban airspace management

- Protection of critical infrastructures (power plants, industrial facilities, logistics hubs)

- Defense of public events and restricted-access areas

- Prevention of illicit activities such as unauthorized surveillance or smuggling

Military and homeland security context:

- Perimeter protection of bases and stategic installations

- Defense of mobile convoys and tactical vehicles

- Integration into electronic warfare platforms 

Technical Requirements and Design Approach

Antennas intended for Counter-UAS systems represent one of the most critical elements in ensuring the overall effectiveness of the platform. Unlike other applications where it is possible to rely on standard or reusable solutions, the C-UAS field requires extremely accurate design work, tailored to the specific use case.

Each platform presents its own distinctive constraints: compact dimensions, low weight, operation in harsh environments, mechanical integration needs, and stingent performance requirements both in transmission and reception. The antennas must operate over specific frequency bands - often spanning multiple octaves - while maintaining stable electrical characteristics across the entire operating range.

In multiband systems, operation must often be divided into multiple sub-bands, each with different geometries and dedicated design measures to prevent coupling and mutual interference between radiating elements. Moreover, the electrical design cannot be separated from the mechanical constraints imposed by installation (fixed, mobile, or portable), nor from the environmental conditions in which the system operates.

For this reason, the design of antennas for C-UAS systems must begin with a combined analysis of the electromagnetic specifications and the physical characteristics of the system, adopting an interdisciplinary approach that enables full optimization of the entire apparatus.

Field experience has shown that relying on standard or generic antennas in such contexts rarely delivers satisfactory results, as only a custom solution can ensure the required precision, reliability, and adaptability to real operational environments - thereby maximizing the overall effectiveness of the C-UAS platform.

Gaining a thorough understanding of the specific requirements of each application enables us to develop custom antennas that deliver the effectivenenss and reliability demanded by modern C-UAS systems.
