The size of the antenna should be calculated from the equation λ=C/f
Cellular phones are called cellular because the zone in which they operate are divided into cells.
We decided to make a quarter wavelength copper Bluetooth antenna
Decision points included:
Bluetooth for its diverse applications making it easier to sell with higher profit.
Copper for its low cost and decent conductivity.
Quarter wavelength as it lowers cost and works well with small range Bluetooth devices.
All members must pass the safety test before entering the clean room
The garments are required to keep the clean room from contamination
Rubber gloves and goggles are needed when working with chemicals
For any questions about the chemicals, there are MSDS sheets available
Copper was chosen as the conductorStrong pointsincluded:
Quarter Wavelength for 2448.5MHzAntenna Length is 30.61mm
The wafers were saw cut with the Micro Automation 1100 diamond saw by lining up the vertical lines and horizontal line to saw each antenna separately.
Planar Antennas are the only devices that can transmit and receive radio frequency waves from a chip.
