sp e - 1 5 - 8 - 0 1 0 / a /ss page 2 of 14 1. introduction t his cggbp.35 35mm*35mm embedded ceramic gps/glonass/beidou patch antenna ha s a wide band of operation , leading to excellent gain and radiation pattern sta bility on all three gnss system bands . c ompared to using a smaller antenna, this will translate into the gnss system having much higher location accuracy, improved reliability of lock in urban areas , better signal reception, with more satellites acquired and a quicker time to first fix. t he patch is mou nted vi a pin and double - sided adhesive. while the antenna will work very well in most device environments (note cannot be covered with metal enclosure), tuning and further optimization of this antenna to different ground - planes and enclosures can be done i f required, als o including a pin length change. these changes would be subject to possible nre and a minimum order quantity. contact your local taoglas sales office for more details. sp e - 1 5 - 8 - 0 1 0 / a /ss page 3 of 14 2. s pecification e lectrical f requency b eidou :1561.098mhz 2.046 m h z g ps: 1575.42 1.023mhz g lonass: 1602 5mhz c entre frequency 1 589 mhz 6 mhz v swr g ps and beidou 2 .5 : 1 max g lonass 1.8 : 1 max b andwidth 3 4 mhz r et u rn loss @ - 10db z enith gain b eidou: +4.0 dbi typ. g ps: +3.0 dbi typ. g lonass: +4.5 dbi typ. i mpedance 5 0 ? m e chanical d imensions 3 5 x 35 x 3 mm m aterial c eramic p in diameter 0 .9mm p in length 2 .15mm w eight 1 3.5g environmental o peration temperature - 40c to 85c s torage temperature - 40c to 105c h umidity n on - condensing 65c 95% rh o riginal patch speci fication tested on 70*7 0mm ground plane taoglas part # cggbpd.35.b sp e - 1 5 - 8 - 0 1 0 / a /ss page 4 of 14 3. a ntenna s11 properties sp e - 1 5 - 8 - 0 1 0 / a /ss page 5 of 14 4. antenna return loss sp e - 1 5 - 8 - 0 1 0 / a /ss page 6 of 14 5. 2 d antenna radiation 5.1 1 561 mhz free space p eak gain (dbi) a verage gain (dbi) x z plane 4 .56 - 0.19 y z plane 4 .66 - 0.08 sp e - 1 5 - 8 - 0 1 0 / a /ss page 7 of 14 5 .2 1575.42 mhz free space p eak gain (dbi) a verage gain (dbi) x z plane 3 .66 - 1.13 y z plane 3 .72 - 1.07 sp e - 1 5 - 8 - 0 1 0 / a /ss page 8 of 14 5 .3 1602mhz free space p eak gain (dbi) a verage gain (dbi) x z plane 5 .37 0 .54 y z plane 5 .2 4 0 .41 sp e - 1 5 - 8 - 0 1 0 / a /ss page 9 of 14 6. mechanical drawing (unit: mm) sp e - 1 5 - 8 - 0 1 0 / a /ss page 10 of 14 6.1 a dhesive thickness sp e - 1 5 - 8 - 0 1 0 / a /ss page 11 of 14 7. c ggbpd.35. b evaluation board (unit:mm) sp e - 1 5 - 8 - 0 1 0 / a /ss page 12 of 14 8. pcb footprint recommendation sp e - 1 5 - 8 - 0 1 0 / a /ss page 13 of 14 9. p ackaging sp e - 1 5 - 8 - 0 1 0 / a /ss page 14 of 14 |
