spe - 14 - 8 - 037 / c /as page 2 of 13 1. i ntroduction t aoglas usa has designed a range of efficient antenna s inside us standard raised non - reflective road marker s . th ese are designed for, and installed inside, the low profile botts dot s that can be mounted directly on the pavement and road in the usa. th ese antenna s exhibit remarkably high efficiencies in such s mall package s and live in a very low profile enc losure. they are designed to be mounted directly on the road, pavement , or manhole cover , just like a standard road marker. the se antenna s have been potte d with the epoxy that is tradi tional ly used to secure the road marker itself to the ground. there are no air gaps whatsoever inside the new type approved road marker with antenna, in order to maintain the mechanical integrity. it is presumed that th e standard black epoxy will also be used to install the road mar ker in its final resting place on the ground . the cab.826 cable assembly is included so the antenna cable can be easily disconnected if desired. this is useful when the antenna is mounted on a manhole cover. if the manhole cover is lifted, the cable will split at the push - pull connectors, preventi ng damage to the cable. spe - 14 - 8 - 037 / c /as page 3 of 13 2. specification electrical band amps gsm dcs pcs frequency (mhz) 824 - 894 880 - 960 1710 - 1880 1850 - 1990 polarization linear impedance (ohms) 50 ohms peak gain (dbi) 2.5 2.5 1 0.6 efficiency (%) 30 28 18 18 return loss (db) - 1 8 - 18 - 1 8 - 16 radiation properties omni - directional max input power (watts) 10 mechanical dimensions height = 1 7.6 mm and diameter = 101.4 mm cable wy - 100 coaxial cable connector fully customizable casing uv resistant pp sealant potting environment al protection ip67 corrosion 5% naci for 96hrs temperature range - 40c to +85c thermal shock 100 cycles - 40c to +85c humidity non - condensing 65c 95% rh shock (drop test) 1m drop on concrete 6 axes cable pull 8 kgf spe - 14 - 8 - 037 / c /as page 4 of 13 3. test set up figure 1. impe dance (left hand) , peak gain , efficiency , and radiation pattern measurements (right hand). * the cellular road marker antenna performance was measured on a piece of concrete, 90 mm thickness. spe - 14 - 8 - 037 / c /as page 5 of 13 4. a ntenna parameters 4 .1. return loss figure 2. return loss road marker in free space and on a p iece of r oad ( c oncrete). 4.2 . efficiency figure 3. efficiency road marker in free space and on a piece of road ( c oncrete). spe - 14 - 8 - 037 / c /as page 6 of 13 4 .3 . peak gain figure 4 . peak gain road marker in free space and on a p iece of r oad ( c oncrete). spe - 14 - 8 - 037 / c /as page 7 of 13 4 .4 . radiation pattern f igure 5 . cellular road marker radiation pattern at 849 mhz on piece of road (concrete) . . f igure 6. cellular road marker radiation pattern at 940 mh z on piece of road (concrete) . spe - 14 - 8 - 037 / c /as page 8 of 13 f igure 7 . cellular road marker radiation pattern at 1840 mhz on piece of road (concrete) . . f igure 8 . cellular road marker radiation pattern at 1950 mhz on piece of road (concrete) . spe - 14 - 8 - 037 / c /as page 9 of 13 . figure 9. cellular road m arker radiation pattern at 849 mhz in free s pace . figure 10. cellular road marker radiation pattern at 940 mhz in free s pace . spe - 14 - 8 - 037 / c /as page 10 of 13 figure 11. cellular road marker radiation pattern at 1840 mhz in free s pace. figure 12. cellular road marker radiation pattern at 1940 mhz in free s pace. spe - 14 - 8 - 037 / c /as page 11 of 13 5. mechanical drawing a. rg.02 antenna 5.1 rg.0 2 antenn 5.1 rg.02 antenna spe - 14 - 8 - 037 / c /as page 12 of 13 note: configuration of bumps or protrusions subject to change without noti ce unit: mm (unless stated otherwise) spe - 14 - 8 - 037 / c /as page 13 of 13 5.2 cab.826 cable assembly |
