P 12311 RF Anechoic Chamber Automated Antenna Radiation

P 12311: RF Anechoic Chamber Automated Antenna Radiation and Gain Measurement System with User Interface Team Members Sheldon Palmer (EE) Danielle Walters (EE) Customer Dr. Jayanti Venkataraman Guide Professor George Slack Technical Advisor SRC For more information, visit https: //edge. rit. edu/content/P 12311/public/Home Mission Key Objectives Introduction Design a rotating platform with a fully automated measurement program that obtains the received power for each degree increment; then plots the radiation pattern, and calculates gain of the antenna. • Must work in the 2. 3 -2. 5 GHz frequency range for use with Bluetooth®, Zigbee®, and Wi-Fi devices • User Friendly: Does not require background knowledge • Antenna mount rotates 180° or 360° • Radiation measurements taken for every 0. 5° or 1° interval • Test must be completely automated through Lab. VIEW An Anechoic Chamber is a testing chamber that measures the far field radiation pattern for transmitter and receiver antenna arrangements. A receive antenna is placed on a rotating platform while the radiation pattern and gain are measured using a spectrum analyzer to enable testing of future senior design antenna projects.
