With more cars becoming hybrid electric and total electric powered, the demand for Electrical and Computer engineers will increase in the auto

industry.

The Volt by GM will be an all electric car. Other manufacturers are also introducing all electric cars

This was a good idea but was scrapped because the solar powered lights would not provide enough illumination.

Opto-electronics (devices that use light) include LEDs or light emitting diodes, solar cells, and fiber optic components

Today wireless communication devices are everywhere. Mobile telephones and PCS (personal-communications-services) devices allow people to be in constant contact throughout the world. Wireless connections to the internet are available. Connections between components in a computer system can be done wirelessly. Everything is getting smaller, lighter, and cheaper. Communications devices will soon be as small as a watch. Future communication devices need a miniature antenna. Your project is to research, and design a planar antenna for use inside a miniature communications device that is the size of a watch. The maximum size of the designed antenna can not exceed 20mm x 20mm. Cost, reliability, and manufacturability is also to be considered in the design. You can chose to design an antenna for a mobile phone operating at either the cellular frequency band of 824 to 894 MHz or the PCS frequency band of 1850-1990 MHz or you can design an antenna for one of the new generation wireless devices that use the Un-Licensed Band (ULB) frequency of 2400 to 2497 MHz. These devices are commonly known as “Bluetooth” or “Wi-Fi” devices. You will then fabricate your design using techniques and processes available in the Microelectronics Clean Room. The final design and the fabrication summary are to be presented to a review team from the department of electrical and computer engineering for evaluation. A formal written report is also required. You will receive instruction on the microelectronics processes and techniques you will need to fabricate this antenna. All fabrication will take place in the Microelectronics Clean Room lab in room 201 of the Cameron Applied Research Center. A list of options and available attributes will be provided. This is a Team project. Teams will need to be formed. Teams will meet as necessary in the Microelectronics Clean Room. All team members will receive the same grade for the project verbal presentation and written report.
