Model Orientation +X +Y ! Model as originally imported 20 January 2003 Rincon Proprietary 2

Model Orientation Antenna 1 Antenna 2 +X +Y ! Model as simplified for FEA modeling ! Chassis top is modeled as solid metal ! Chassis bottom is ABS/PC Blend 20 January 2003 Rincon Proprietary 3

Antenna Description ! Monopole antennas extend 29.75 mm below the bottom of the metal part of the chassis. ! Antennas are placed at the front left (below the toroid) and back right of the ZonePlayer ! Wire diameter corresponds to the center conductor of RG-402 (.141 inch outer diameter) cable. 20 January 2003 Rincon Proprietary 4

Measurements in Toyon’s Anechoic Chamber ! We measured return loss for both ZonePlayer antennas as well as patterns over the three principal planes (XY, XZ, and YZ) ! Pattern measurements are realized gain measured at the receiver, including the losses due to the cable and connector of roughly 1- 1.25 dB. ! As in the computer modeling, Antenna 1 is at the front left of the ZonePlayer and Antenna 2 is at the back right. ! Both horizontal and vertical polarizations are plotted. ! Polarization convention is in the reference frame of the ZonePlayer, not the chamber. – If the ZonePlayer is resting on its side, then vertical polarization in the ZonePlayer reference frame is horizontal in the chamber reference frame. 20 January 2003 Rincon Proprietary 6

Pattern Orientation ! The first four patterns are measured with the ZonePlayer sitting on its feet on a rotating pedestal. – Both Antenna 1 and Antenna 2 are measured, and both standard linear polarizations are shown for each. ! The second four patterns are measured with the ZonePlayer on its back (not on its top). ! The last four patterns are measured with the ZonePlayer on its side. 20 January 2003 Rincon Proprietary 7

Results ! Radiation is mainly vertically polarized as expected. – Horizontal polarization is lower by 5-10 dB. ! Pattern coverage shows some masking due to the ZonePlayer chassis but is generally broad. – This is about as close to ideal as you can get without putting the antennas outside and on top of the chassis. ! The second set of patterns shows that the highest gain for each antenna is actually out the side opposite the antenna. – This is not intuitive, but it matches the simulation results. 20 January 2003 Rincon Proprietary 21
