22 doc.: IEEE /0995r1 Submission September 2009 Tian-Wei Huang, National Taiwan UniversitySlide 22 Multi-path Measurement d : the distance between two antenna Theta : the angle of horn rotating anti-clockwise 15 cm Table Tx : Omni-antennaRx : horn LNA Theta d

23 doc.: IEEE /0995r1 Submission September 2009 Tian-Wei Huang, National Taiwan UniversitySlide 23 Multi-path Measurement To achieve rotation, the receiver part slightly moves forward. Then it is able to raise the tail of LNA to realize angles of rotation. Rx : horn LNA Rx : horn LNA Table Theta 2cm

24 doc.: IEEE /0995r1 Submission September 2009 Tian-Wei Huang, National Taiwan UniversitySlide 24 Multi-path Measurement d = 30cm The peak has 0.059ns difference, about 1.8cm difference in distance. When rotating the horn antenna, the horn slightly move forward for 2cm.

25 doc.: IEEE /0995r1 Submission September 2009 Tian-Wei Huang, National Taiwan UniversitySlide 25 Multi-path Measurement d = 30cm 19.7dB 0.368ns For Theta = 20, the first peak and second peak has 11.03cm difference in distance.
