Wideband communication characteristics for two different geometrical configurations of a gymnasium at 57.5 GHz are in¨estigated. Shooting and bouncing rayrimage techniques are applied to compute the impulse response. By using the impulse response of these multipath ( channels, the outage probability

✦ Synopsis
Input impedance of the antenna of Figure 13 ( Z ,) = 300
5. CONCLUSION
This articlc outlines a simple mcthod for studying any sinuous antenna. The results obtained with this method are found to bc in good agreement with those obtained with a rigorous surface moment method and with experimental measurements.
A number of proposals have been advanced for the optimization of the sinuous antenna parameters in order to obtain a lower cross-polarization level. Moreover, we have shown that the broadband behavior is relatively good for constant parameters.
Furthermore, we have shown that the coupling between two sinuous antennas is small even for low frequencies.
