Services – an overview

At Harp Technologies, we are proud of our competence, expertise, and capabilities in RF, microwave, and millimetre wave technology. Our personnel are used to working with the most demanding specifications. This enables us to serve our customers in the development of better products or in the development of methods and technology to acquire critical measurement data.

The services provided by Harp Technologies are divided into three categories: Studies and analyses, Components, and Systems. Considering customers’ R&D cycles, Harp Technologies provides services that cover the whole range from concept and feasibility studies to the development of a prototype or a small series and turning the design into mass production. We can help our customers in any single step of the R&D cycle or provide a complete turnkey solution.

Determined to provide our customers with the best value, Harp Technologies is constantly improving its capabilities in design and development. We have a wide range of leading design software tools, including the CST MICROWAVE STUDIO® 3D electromagnetic design and simulation software, the AWR Microwave Office® RF/microwave circuit design software, the KeyCreator™ mechanical CAD software, and Matlab® for scientific computing. These cutting-edge tools help us to provide our customers with accurate design results and fast development cycles. We also have ESD-protected prototyping and testing facilities equipped with an extensive set of equipment for electrical measurements and environmental testing, enabling us to make measurements up to 125 GHz in a temperature range from -40°C to +180°C. If wider ranges in frequency or temperature are needed, please contact us and we will find a solution.

 

 

Studies and analyses

The Studies and analyses service category encompasses, on one side, theoretical work in the form of studies, for example pre- or feasibility studies. On the other side, various electromagnetic analyses are offered, such as antenna pattern and performance analyses (including the surrounding environment, if needed), analyses of electromagnetic heating effects, and electromagnetic compatibility (EMC), electrostatic discharge (ESD), and radar cross-section (RCS) analyses. Furthermore, we provide consultancy in the field of RF, microwave, and millimetre wave engineering, e.g. to improve your design in terms of EMC, antenna design, or antenna matching. Within this service category, we have assisted our customers in a large number of assignment for various applications – selected examples including:

  • electromagnetic simulations of the thermal effects of microwaves in an industrial application
  • feasibility study of wireless communication techniques for a logistics application
  • antenna performance simulations, design optimisation, and tuning of the matching circuit of a hand-held device for industrial applications
  • antenna tuning of a multi-antenna device for a safety application
  • antenna design and tuning of the matching circuit for wearable device for a consumer application
  • study and preliminary design of a spaceborne remote sensing instrument, including all its subsystems (antennas, receivers, signal processing, calibration, etc.)
  • feasibility study and simulations of a novel antenna concept for a telecommunication application
Simulated surface currents on an aircraft
As an example of work conducted in the Studies and analyses service category, this figure presents simulated surface currents on an aircraft induced by lightning striking the nose of the aircraft. In this particular case, the size of the structure that was analysed is relatively large, measuring approximately a hundred wavelengths.

 

 

Components

The Components category encompasses the design and product development of customised RF, microwave, and millimetre wave components and modules. Examples include antennas for various devices, frequency bands, and applications; active components (such as amplifiers, up- and downconverters, and oscillators); and passive components (such as filters and couplers). Both planar and waveguide technologies are supported. The services provided range from specification and component concept design up to the development and delivery of small series of components, qualified according to generic (e.g. MIL, ECSS, etc.) or customer-specific specifications.

Low-mass array antennas
Low-mass array antennas, developed by Harp Technologies, for the altimeter breadboard of a planetary lander. The gain of the antennas is 22 dB in the Ku band.
Waveguide passband filters in compact design
Waveguide passband filters in compact design, developed by Harp Technologies. The filters are silver-coated for maximum surface conductivity and for minimum losses.

 

 

Systems

The Systems service category embraces the design and development of subsystems and whole systems, such as self-standing instruments. The services provided range from the specification and design of a subsystem or system up to the development and delivery of small series and hand-over to mass production. Qualification can be made according to generic (e.g. MIL, ECSS, etc.) or customer-specific specifications. In particular, our competence and experience in the development of active and passive radio sensors (radars and radiometers) and their subsystems is world-class. Radio sensors are employed for a variety of purposes, including remote sensing, defence and security, industrial, and scientific applications.

Radio Frequency Interference (RFI) processor
Radio Frequency Interference (RFI) processor, under development by Harp Technologies, for detecting and mitigating harmful RFI measured by passive microwave remote sensing sensors. In practice, the RFI processor is a high-performance signal processor that applies special algorithms to detect low intensity RFI.
