I. Overview of UWB technology and application of high-precision positioning
UWB technology is a technology that uses narrow pulses for wireless transmission, and its signal bandwidth is usually more than 500MHz. This technology can achieve centimeter-level positioning accuracy, and provides a strong technical support for a variety of scenarios requiring accurate position information.
In the field of intelligent logistics and intelligent warehousing, the deployment of UWB positioning system can track the precise location of goods and personnel in real time, achieve intelligent warehouse management, and improve work efficiency.

Second, high-precision positioning UWB chip cost analysis
As the core component to realize the UWB positioning function, the cost of high precision positioning UWB chip is complex and involves many aspects.
Research and development cost
Research and development cost is an important part of UWB chip cost. This includes the compensation of the research and development team, the acquisition and maintenance of research and development equipment, and the costs incurred during the experimental testing and validation process. In order to design a UWB chip with excellent performance, low power consumption and controllable cost, the R & D team needs to continuously carry out technical research and innovation to maintain a high degree of consistency with market demand.
In order to reduce research and development costs, enterprises can adopt the following strategies: first, strengthen cooperation and exchanges with innovative advanced enterprises, introduce advanced technology and research and development experience; The second is to optimize the research and development process, improve the efficiency of research and development, reduce unnecessary expenses; The third is to increase investment in research and development teams, improve the skills and quality of research and development personnel, and ensure the quality and competitiveness of research and development results.
Production cost
Production cost refers to the expenses required to convert research and development results into actual products, including raw material procurement, depreciation of production equipment, and operation and maintenance of production lines. With the continuous improvement of the production process and the play of scale effects, the production cost is expected to gradually reduce.
In order to reduce production costs, enterprises can take the following measures: first, optimize the production process, improve production efficiency, and reduce the production cost per unit of product; The second is to strengthen supply chain management to ensure the stable supply of raw materials and price advantages; The third is to improve the utilization rate and maintenance level of equipment, and reduce equipment failures and downtime.
Market cost
The market cost mainly involves the investment in product promotion, sales channel construction, after-sales service and so on. In order to bring high-precision positioning UWB chips to the market and gain user recognition, enterprises need to invest a lot of resources for marketing and brand building.
In terms of marketing, enterprises can adopt a variety of strategies, such as participating in industry exhibitions, holding technical seminars, and launching partner programs to expand their visibility and influence. At the same time, enterprises should also pay attention to the construction and improvement of after-sales service system, provide timely and professional technical support and solutions, and improve customer satisfaction and loyalty.
Combined with the above factors, the cost of high-precision positioning UWB chips is relatively high. However, as the technology continues to mature and the size of the market expands, the cost of chips is expected to gradually reduce. In addition, the government's support policies for the Internet of Things industry and the cooperation and collaboration of upstream and downstream enterprises in the industrial chain will also help reduce the cost of chips and promote the popularization and application of UWB technology.
3. Technical characteristics of UWB antenna
As a key component of high precision positioning, UWB antenna's performance directly affects the accuracy and stability of positioning system. The following are the main technical features of UWB antennas:
Broadband features
Ultra-wideband UWB antennas have a wide band range and can cover the operating frequency band of UWB signals. This wide band feature ensures the integrity and stability of the signal during transmission, effectively avoiding signal loss or distortion caused by frequency band restrictions.
High gain characteristic
In order to improve the transmission distance and receiving sensitivity of the signal, UWB antennas usually adopt special design and structure to achieve high gain performance. The high-gain antenna can focus and transmit the signal better, enhance the transmission effect of the signal, and improve the positioning accuracy.
Multipath inhibition
In complex environment, the multipath effect is one of the main factors affecting the positioning accuracy. Multipath effect refers to the phenomenon of reflection, refraction and scattering when the signal meets obstacles in the propagation process, resulting in the receiving end receiving multiple signals of different paths. These signals interfere with each other, making the positioning accuracy decreased. The multi-path effect can be effectively suppressed and the positioning accuracy can be improved by optimizing the design and signal processing algorithm of UWB antenna.
In order to realize multipath suppression, the design of UWB antenna needs to consider the antenna radiation pattern, chemical characteristics and signal processing strategy. For example, the use of differential antenna structures or array antenna technology can enhance the ability to receive signals in a specific direction, while suppressing interference signals from other directions. In addition, combined with advanced signal processing algorithms, such as time reversal multipath suppression algorithm, the influence of multipath effect on positioning accuracy can be further reduced.
Miniaturization and integration
With the trend of miniaturization and integration of Internet of Things devices, UWB antennas also need to have corresponding characteristics. By using advanced materials and processes, antennas can be miniaturized and integrated to facilitate deployment and application in various types of equipment. The miniaturized and integrated UWB antenna can not only reduce the overall size and weight of the device, but also help to reduce production costs and power consumption, and improve the portability and practicality of the device.
To achieve antenna miniaturization and integration, designers often employ advanced materials such as ceramics, plastics or composites to reduce the weight of the antenna and improve mechanical properties. At the same time, compact antenna structures such as microstrip antenna and coplanar waveguide antenna are also widely used to achieve the miniaturization of antennas. In addition, by using multi-layer printed circuit board technology or 3D printing technology, the antenna can be integrated with other circuit elements to achieve a higher degree of integration.
Fourth, the design difficulties of UWB antenna
Although UWB antenna has many advantages, it also faces some difficulties and challenges in the design process.
Broadband matching problem
Since UWB signals have a wide band range, antennas need to maintain good impedance matching in the wide band. This requires antenna designers to achieve good return loss and radiation efficiency in the wide band to ensure effective signal transmission.
Multi-band coverage problem
In some application scenarios, UWB antennas may need to cover several different frequency bands at the same time. This requires antenna designers to fully consider the interaction and interference between different frequency bands in the design process to ensure that the antenna can maintain good performance in multiple frequency bands.
Anti-interference capability
In practical applications, UWB antennas may be subject to interference from other wireless communication systems. In order to improve the anti-interference ability of the antenna, designers need to adopt effective filtering and isolation technology to reduce the impact of interference signals on UWB signals.
V. Application prospect of UWB antenna
With the rapid development and popularization of Internet of Things technology, UWB antennas have broad application prospects in various fields.
