Case analysis: Cowin GPS / BeiDou + GSM combined dual frequency antenna helps interconnected medical to realize ultra accurate positioning and IOT technology.
Customer Background:
Shanghai Bangbang Robot co., Ltd. is a high-tech industrial modernization company integrating independent research and development, production and sales of intelligent auxiliary products with the initial intention of helping people with disabilities to return to normal life. Bangbang Robot is committed to using intelligent technology to bring a healthy life, and constantly build intelligent solutions for future health and ecological care, creating a respected national brand in the global field of helping the elderly and the disabled.
Business requirements:
GPS+ Beidou +GSM combined into a shell, positioning accuracy within 10M.
The challenge:
For disabled people, timely and effective real-time monitoring plays a crucial role. Take a disabled person out for example, the positioning accuracy is not enough for medical staff to spend a lot of time to find, and unstable communication cannot allow the disabled person to quickly launch SOS for help, which has proved to be challenging in the development of technology. Digital transformation, with round-the-clock monitoring, can help make more informed decisions about the health, activities and care of people with disabilities, and ultimately improve their health and quality of life
Problem Description:
The customer can provide a space size of 50* 40MM to place the antenna, and the positioning antenna and GSM antenna should be placed in this space. The small space represents the mutual interference of the antenna before, and the engineer plays a crucial role in the debugging result of the isolation degree.
Solution:
1. Bangbang Intelligent knows that GPS antenna is very important to achieve accuracy within 10M, and finally chooses to cooperate with gonggong after controlling different antenna products.
2. A core requirement is that common antenna solutions can use the circuit board as a ground plane to prevent interference from other RF signals and thus prevent damage to GPS accuracy.
3. Two LNA amplifiers and a front-end SAW filter are configured on an 18*18MM ceramic chip to greatly reduce out-of-band noise. The antenna composed of bipolar amplifiers makes its effective gain up to 28-30dB.
4. According to the size of the space, engineers choose spiral sensing antenna to match the resonant frequency of GSM, 800-920mhz / 1710-1900mhz up to 3.3dB gain and 68% efficiency.
5. The high density epoxy glass cloth laminate is used for isolation of the two antennas before, and the isolation degree is up to 25DB, which effectively solves the difficulties of mutual interference of signals.
6. The overall size of the antenna after the final combination is 45* 35MM in length, which is qualified by Bangbang Robot.
Economic benefits:
The customer successfully introduced the product to the market and has achieved sales of 20,000 units.
