  1. Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: [Reference pattern models for phased antenna arrays] Date Submitted: [November 2006] Source: [Alexei Davydov, Alexander Maltsev, Alexey Rubtsov, Ali Sadri] Company: [Intel Corporation] Address: [Intel Corporation, 603950 Turgeneva 30, Nizhny Novgorod, Russia], E-mail: [alexei.davydov@intel.com, alexander.maltsev@intel.com, alexey.rubtsov@intel.com, ali.sadri@intel.com] Abstract: [This contribution describes reference antenna pattern models for N-element antenna array] Purpose: [Contribution to 802.15 TG3c at July 2006 meeting in San-Diego, USA] Notice: This document has been prepared to assist the IEEE P802.15. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributor acknowledges and accepts that this contribution becomes the property of IEEE and may be made publicly available by P802.15. Alexander Maltsev (Intel Corporation)

  2. Goal • This contribution proposes reference antenna pattern model for N-element antenna array (over metal plate) that may be used for performance comparison of mmWave systems Alexander Maltsev (Intel Corporation)

  3. N-element antenna array in free space Normalized angle factor: Antenna pattern: Alexander Maltsev (Intel Corporation)

  4. Single dipole over metal plane Angle factor: Alexander Maltsev (Intel Corporation)

  5. Antenna pattern for N-element antenna array over metal plane N-element antenna array over metal plane: Antenna pattern: Antenna pattern for phased antenna array (adaptive beam steering): Alexander Maltsev (Intel Corporation)

  6. Simulation scenarios for antenna array • Scenario 1: • Saleh-Valenzuela channel model • LOS:fixed direction of LOS ray • N-element antenna (over metal plane) with fixed direction of beam • Scenario 2: • Saleh-Valenzuela channel model • nLOS:LOS ray is removed • N-element antenna (over metal plane)with fixed direction of beam • Scenario 3: • Saleh-Valenzuela channel model • nLOS:LOS ray is removed • N-element antenna (over metal plane)with adaptive beam steering (to the strongest ray) Alexander Maltsev (Intel Corporation)

  7. Parameters of Saleh-Valenzuela channel model [1] Alexander Maltsev (Intel Corporation)

  8. Simulation results:Examples of effective channel realizations (Scenario 1) N=1 N=4 NOTE: Channel frequency response for 1280 MHz bandwidth was obtained by using 1024-point FFT (1.25 MHz spacing for frequency tones). Alexander Maltsev (Intel Corporation)

  9. Simulation results:Examples of effective channel realizations (Scenario 1) N=8 N=16 NOTE: Channel frequency response for 1280 MHz bandwidth was obtained by using 1024-point FFT (1.25 MHz spacing for frequency tones). Alexander Maltsev (Intel Corporation)

  10. Backup Alexander Maltsev (Intel Corporation)

  11. - channel (power) gain for j-th tone of t-th realization • number of frequency tones • number of simulated channel realizations Channel indicators Effective channel gain and channel deviation for given channel realization: Effective channel gain: Intra-realization channel max/min deviation: Inter-realization standard deviation of effective channel gain: Alexander Maltsev (Intel Corporation)

  12. Simulation results: Channel indicators for Scenario 1 For Scenario 1 (LOS) N-element antenna array provides effective channel gain increasing with significant reducing the frequency selectivity. Alexander Maltsev (Intel Corporation)

  13. Simulation results: Channel indicators for Scenario 2 Alexander Maltsev (Intel Corporation)

  14. Simulation results: Channel indicators for Scenario 3 Alexander Maltsev (Intel Corporation)
