Antennas and RF systems from concept to mass production

Sevskiy GmbH in Munich

We are an independent, owner-managed development company for antenna and high-frequency technology in Munich. Our work begins where radio performance, installation space and real installation conditions have to be brought together. We develop new solutions, optimize existing systems and adapt our own products to customer-specific requirements. The agreed technical scope determines whether we take on a single issue or the entire development process.

Development for the specific application

An antenna works in interaction with its surroundings. Housing, circuit board, battery, cable and neighboring electronics influence impedance matching, radiation and reception. We therefore record frequency bands, installation situation, interfaces and target values at the beginning of the task. Our development areas include, among other things, IoT, vehicle technology, industrial radio technology, navigation and satellite-based connections. There are also microwave applications and magnetic coupling for wireless energy and data transmission.

• Individual antennas and integrated antenna systems
• RF modules for communication, navigation and sensors
• Feasibility assessment, optimization and product customization

The entire RF signal path at a glance

We look at radiators, matching networks, filters, amplifiers and signal distribution together with connectors, cables and circuit board transitions up to the RF chip. Losses in front of the first receiving amplifier have a different effect than losses elsewhere in the system. Good impedance matching alone does not describe good antenna radiation. Through circuit analysis, 3D field simulation and targeted measurements, we differentiate between such causes and derive suitable changes.

• Antenna geometry, feed network and polarization
• Filter, LNA and active receive paths
• RF layout, return current paths and critical transitions

Collaboration with transparent decisions

We coordinate tasks, target values and deliverables with your development team. In the project, we explain model assumptions, compare variants and document the results of the agreed investigations. Regular technical coordination and, if necessary, on-site support help to bring together electrical and mechanical changes. You will receive concrete recommendations and traceable documentation so that design, electronics development and production can continue to work at a coordinated level.

• Clear technical interfaces and agreed test criteria
• Comparison of simulation and measurement
• Documented changes and results

Prototypes, production documents and quality from one source

Our own prototyping and the RF laboratory enable short distances between design, construction and examination. We complement CNC machining, 3D printing and electronics assembly with specialized manufacturing partners. For the transition to mass production, we consider manufacturability, assembly, material selection and testing access. If requested, we can handle mass production with suitable partners and supervise production. We determine test characteristics and quality requirements for each product and record them in the agreed documents.

• Functional and integration prototypes
• Parts lists, drawings and manufacturing data
• Test concept, production support and quality control
