sp e - 14 - 8 - 07 1 / c /ss page 2 of 15 1. introduction this 18 mm *18mm square ceramic gps/glonass/beidou patch antenna 's wide band of operation leads to excellent gain and radiation pattern sta bility on all three gnss system bands . compared to using a smaller antenna, this will translate into the gnss system having much hig her location accuracy, improved reliability of lock in urban areas , better signal reception, with more satellites acquired and a quicker time to first fix. the patch is mounted vi a pin and double - sided adhesive. sp e - 14 - 8 - 07 1 / c /ss page 3 of 15 2. specification electrical frequency be idou:1561.098mhz 2.046 m h z gps: 1575.42 1.023mhz glonass: 1602 5mhz centre frequency 1583mhz 3 mhz vswr beidou: 2. 8 max. gps: 2 .8 max. glonass: 1.8 max. bandwidth 26 mhz r et u rn loss @ - 10db zenith gain beidou: +3.0 dbi typ. gps: +2 .0 dbi typ. glona ss: +4.0 dbi typ. impedance 50 ? mechanical dimensions 18*18*4mm material ceramic pin diameter 0.9mm pin length 1.65mm environmental operation temperature - 40c to 85c storage temperature - 40c to 105c humidity non - condensing 65c 95% rh *me asured on a 70*70mm ground plane sp e - 14 - 8 - 07 1 / c /ss page 4 of 15 3. antenna characteristics 3.1 s11 impedance sp e - 14 - 8 - 07 1 / c /ss page 5 of 15 3.2 return loss sp e - 14 - 8 - 07 1 / c /ss page 6 of 15 4. 2d antenna radiation sp e - 14 - 8 - 07 1 / c /ss page 7 of 15 4.1 1575.42mhz free space peak gain (dbi) average gain (dbi) xz plane 2.57 - 1 .97 yz plane 2.56 - 2 .0 7 sp e - 14 - 8 - 07 1 / c /ss page 8 of 15 4.2 1561mhz free space peak gain (dbi) average gain (dbi) xz plane 3.32 - 1.18 yz plane 3.45 - 1.11 sp e - 14 - 8 - 07 1 / c /ss page 9 of 15 4.3 1602mhz free space peak gain (dbi) average gain (dbi) xz plane 4.72 0.08 yz plance 4.52 - 0.08 sp e - 14 - 8 - 07 1 / c /ss page 10 of 15 5. mechanical drawing 5.1 adhesive thickness sp e - 14 - 8 - 07 1 / c /ss page 11 of 15 red line shows t he adhesive without liner C thickness 0.08~0.1mm sp e - 14 - 8 - 07 1 / c /ss page 12 of 15 6. cggbpd.18.a evb sp e - 14 - 8 - 07 1 / c /ss page 13 of 15 7. pcb footprint recommendation cggbp.18. 4.a.02 patch on 70*70mm ground plane sp e - 14 - 8 - 07 1 / c /ss page 14 of 15 8. packaging 8.1 inner tray per tray: 25 pieces 25 pieces per tray 8 tray s per carton sp e - 14 - 8 - 07 1 / c /ss page 15 of 15 8.2 carton per carton (inside box) C 8 trays = 2 00 pieces outer carton (outside box) C 4 cartons = 8 00 pieces |
