ECE 595C - RF and Microwave Wireless Components

Lecture Hours: 3 Lab Hours: 2 Credits: 4

Counts as:

Experimental Course Offered: Spring 2006

Catalog Description:
This course is an introduction to the high frequency portion of wireless systems. The course will utilize both electromagnetic and circuit theory combined with a measurement laboratory to give students a grasp of the concepts necessary to understand high frequency wireless systems. Microwave software will be used to design components focusing on the antennas, passive components, active circuits, and packaging of wireless systems. Noise, propagation, and modulation will also be introduced to put the relevance of the component design in the context of a wireless system.

Supplementary Information:
Engineering Design Content:

The design will center on the creation of wireless radio systems, focusing on WLAN radio components.

Synthesis will be performed in the creation of filters and antennas using microwave software in con junction with analytical hand analysis.

Fabrication will be performed utilizing the results of the synthesis of the filters and antennas.

Measurement will be performed on the fabricated structures using vector network analyzers, spectrum analyzers, and high frequency oscilloscopes.

Engineering Design Considerations:

The course will discuss spectrum allocation and health concerns from radiation and the relationships between power output of wireless systems. The performance of the lab projects will be discussed in regards to these concerns.

Labs

There will be 4 to 5 students per group arranged by the professor. We will be running 2 to 3 lab sessions. These will be arranged.

Laptop Computers

6 Laptops will be issued to the laboratory groups. Each is equipped with the necessary software, specifically, Ansoft HFSS and Agilent ADS. Once there are issued, they are your responsibility. Any damage that occurs is your own responsibility and a grade will not be given unless these are returned in their original working order. This includes viruses, so safe computing practices is essential.
