Quarterwave is a leading innovator in wireless communication, specializing in advanced antenna solutions. The company designs tailor-made antennas for different applications like Ultra-Wideband (UWB), 5G, Wi-Fi, and other radio frequencies to provide stable and clear transmission across the spectrum. These antennas are designed in a way that carefully strikes a balance between high sensitivity, broad bandwidth, and interference mitigation.
As devices become more compact and densely packed with electronic components, the risk of EMI escalates, particularly in the automotive, telecommunications, IoT, and medical sectors. Quarterwave addresses these challenges through advanced Ultra-Wideband (UWB) technology, ensuring broad frequency coverage and high EMI resistance. Ultra-Wideband (UWB) technology is gaining significant traction in Smart Home and Automotive applications. Quarterwave has developed a groundbreaking antenna solution that utilizes the existing PCB (Printed Circuit Board) as the antenna, eliminating the need for additional components and drastically reducing costs. Initial prototypes have shown an impressive efficiency exceeding 80% across the 5 to 10 GHz frequency spectrum.
With a strong commitment to research and development, the company delivers tailored solutions that enhance connectivity and efficiency across industries, including automotive, industrial, smart home, IoT, energy, and professional audio.
Quarterwave's comprehensive suite of services includes:
- Design: Crafting high-performance antennas tailored to specific applications.
- Simulation: Using advanced modeling tools to enhance antenna performance and meet EMC requirements.
- Measurement: Conducting precise validations for EMC compliance.
- Prototyping: Developing functional models for rigorous testing before mass production.
- EMC/EMI Testing: Ensuring devices meet regulatory requirements and perform optimally in real-world environments.
One of the most crucial tools in this process is antenna simulation. This enables engineers to model, analyze, and optimize antenna performance long before physical prototypes are constructed. The 2.5D simulations, such as Momentum simulations, are vital in antenna development for their balance of accuracy and efficiency, allowing engineers to analyze critical performance parameters like impedance and radiation patterns. The 3D simulations, like FEM and Time Domain Simulations, are crucial for antenna development due to their ability to provide highly accurate and detailed insights into performance. These simulations enable engineers to analyze complex geometries and interactions within the antenna design, allowing for precise evaluations of parameters such as radiation patterns, gain, and efficiency.
Antenna measurement is another essential step in the design process. Stand-alone antenna performance is ensured by analyzing the antenna in isolation, optimizing key parameters like gain, efficiency, polarization, and radiation pattern. Integrated Antenna Performance is measured once the antenna is integrated into the device, as factors like diffraction, coupling, and interaction with other components influence its performance. Over-the-air (OTA) measurements such as Total Radiated Power (TRP), Total Isotropic Sensitivity (TIS), Effective Isotropic Radiated Power (EIRP), and Effective Isotropic Sensitivity (EIS) are used to assess the device's overall radio performance. In addition to standard antenna measurements, Quarterwave also offers Error Vector Magnitude (EVM), Symbol Interference analysis, Adjacent Channel Power Ratio (ACPR), Bit Error Rate (BER) testing, and Modulation Accuracy assessments.
Quarterwave's latest innovation, the PREOTA Box, is set to revolutionize antenna measurement technology, making high-precision Over-The-Air (OTA) testing more accessible and cost-effective. It is a compact and innovative tool measuring just 45 cm x 45 cm x 45 cm. It combines physical precision with advanced technology to streamline your measurement process. It can replace expensive communication testers with an intelligent integration of affordable software-defined radios (SDRs) and specialized software tools.
Beyond providing top-tier antenna components, Quarterwave collaborates with customers throughout the entire product development lifecycle. From initial concept and prototyping to testing and final deployment, the company ensures seamless integration and superior performance.
