5 doc.: IEEE 802.22-08/0308r0 Submission September 2008 Gerald Chouinard, CRCSlide 5 Main beamwith based on cos 4 (+/- 72°) to cover for lowest UHF frequencies (TV channel 14 at 473 MHz) Backlobe and cross-polar discrimination at -20 dB relative to maximum antenna gain –Somewhat more demanding than typical DTV receive antennas –Will be achievable with better quality TX/RX antennas designed for WRAN operation to control antenna matching (VSWR) for given range of frequency to protect the HPA –Note that this control of VSWR is much less needed in the case of TV receive antennas Rationale

6 doc.: IEEE 802.22-08/0308r0 Submission September 2008 Gerald Chouinard, CRCSlide 6 Proposed modification to the 802.22 Draft 8.12 CPE transmit/receive reference antenna pattern The WRAN transmit/receive antenna at the CPE shall meet the reference antenna pattern depicted in Figure 159. This pattern was developed assuming a typical antenna gain of 12 dBi and is described by the following equations: Maximum relative gain (dB)= 10*log(cos^4(θ))-72º < θ < +72º = -20-180º < θ < -72º and 72º < θ < 180º Figure 159 CPE TX/RX reference antenna pattern
