Students will increase the signal strength of a wireless network. To boost the strength, students will design and build a cantenna – an antenna made out of a metal can and several other parts. Students will build several cantennas and measure the signal strength and/or the signal-to-noise ratio (SNR) for their cantenna samples to investigate how can diameter, length, and signal source placement affect the cantenna performance.
Submit Challenge Solutions by April 24, 2015 to STEMChallenge@MBRT.org. Include the name of the school, teacher, and students submitting the challenge. Questions about the challenge may also be sent to the aforementioned e-mail address.
Instructional resources to support challenge implementation are forthcoming.
