January 2006 doc. : IEEE 802. 15 -15 -06 -040 -00 -003 c Measurement Setup • An Anritsu 37397 Vector Network Analyzer (VNA) was used to measure the channel transfer function. • The outputs of the amplifiers where connected to the antennas used in the experiment. • The two antennas were mounted on tracks and the directional receive antenna was attached to an electronically steerable platform that permitted the angle of the antenna to be precisely and automatically controlled • In this setup the VNA was set to sweep between 5565 GHz with a frequency step of 6. 25 MHz for 1601 data points.

January 2006 doc. : IEEE 802. 15 -15 -06 -040 -00 -003 c Measurement Setup • An omni-directional antenna is employed at the transmitting side • A 21 d. Bi directional pyramidal horn antenna at the receiving side. • The antennae voltage standing wave ratios were better than 1. 5: 1 over the entire frequency of interest. • The antennae were mounted on rails that permit the precise and automatic positioning required at 60 GHz (5 mm wavelength). • For Ao. A measurements a directional antenna was mounted on an electronically steerable platform for precise angular measurements from 0 to 360 degrees in 4 degree steps. • For each angle the time impulse response was be measured.
