Case study: Cowin Antenna WIFI dual band (2.4/5G) flexible antenna empowers Atari brand game consoles with strong signal communication
Customer background:
Xiezhu Technology is a one-stop service provider for domestic smart hotels and intelligent scenarios, providing the industry with a leading hotel intelligent service solution integrating software + hardware + Internet, Combining intelligent hardware and software to provide a full range of services for hotels and apartments to quickly transform into "future hotels" and "future apartments". Based on "platform + terminal + application" to upgrade the hotel in an all-round way, it adopts the industry's first zero-wiring, non-stop strong electric guest control installation solution that integrates multiple equipment control, scene customization, and products into one body, creating a variety of intelligent scenes, so that Customers experience more comfortable, more convenient and more personalized services. Through all-round information integration and big data analysis, the hotel can be effectively managed, thereby improving hotel revenue and customer satisfaction.
Antenna performance requirement:
Industrial grade WIFI6, frequency distribution in 2.4-2.5G/4.9-6G/5.925-7.125G
The challenge:
The wide application of intelligent scenarios and the substantial increase in the number of wireless terminal access have put forward higher requirements for wireless access bandwidth, concurrent number, and delay, corresponding to higher throughput and faster speed, and supporting more Concurrent connection, a total design of multiple antennas can communicate with multiple terminal devices at the same time, the introduction of MU-MIMO technology can better meet the needs of increasing network speed and connecting more devices. 1800Mbps high-speed performance, support 160MHz bandwidth, equipped with 17 built-in antennas.
Problem Description:
The customer can provide a space for placing antennas with a length of 250*width of 250MM. At the same time, 17 antennas (5 2.4-2.5G, 8 4.9-6G, 4 5.925-7.125) should be placed in this space, and the VSWR of all antennas is less than 2. The gain is higher than 4DB, the efficiency is higher than 60%, and the isolation is higher than 20%. The small space means that the antennas interfere with each other before, and engineers play a vital role in the debugging results of the isolation.
Solution:
1. The customer provides the original product model (including the shell and the finished circuit board), the circuit diagram of all the circuit boards, the mechanical assembly drawing and the material of the plastic shell.
2. Based on the above materials, the engineers will conduct antenna simulation and design the antenna according to the actual environment.
3. The determination of the antenna position and the space given by the structural engineer. For this reason, we define the size of the antenna aluminum alloy substrate as length 240*width 220MM, and 17 antennas are evenly distributed.
4.17 antennas are fixed on the substrate with copper vibrator structure and rivets.
5. The final antenna sample has passed the customer's actual test and acceptance.
Economic benefits:
The customer has successfully launched the product to the market and has achieved sales of 10,000 units.
