System for Next-Gen Wireless Devices
|Duration:||Fall 2018 - Spring 2019|
With the widespread of wireless communication devices, there is an ever-growing demand for portable, low-cost, and easy to use devices that are capable of evaluating the electromagnetics performance of antennas or wireless devices/systems. Conventional measurement systems are very accurate but, in meantime, they are also bulky and expensive. This limits their use in field measurements, in classrooms, as well as in everyday life.
- Basic Board(Explorer Board)
- 2.4 GHz Antennas
- Operating system(Raspbain)
- Soldering equipment
- Raspberry Pi 3 B+
- WIFI Adapter Wireless USB Adapter
- Raspberry Pi Foundation
- The device must cost under $1000
- Easy to carry
- Error correction on transmitted data
- Design an antenna characterization system for next-generation wireless devices to visualize the properties of an antenna system in an easy way and provide educational material to explain these properties to non-specialists.
- The device should test and show the impedance, total efficiency of antennas real time. At the same time, it should be portable and low-cost.
- We decide that the impedance and total efficiency to be our major measurement, if got more time, we may measure parameters as well. For the first three months, our major task is to assemble the prototype then test and improve it.
|The Diagram above illustrates how we will generate a signal with an antenna with known values, as seen on the left, and use our raspberry pi to measure and acquire the data from our unknown antenna for characterization. Characterization can either take place on the receiving raspberry pi itself or the computer can characterize the antenna. The computers main purpose is for visualization of our data.|
