spe - 14 - 8 - 104/ b /ss page 2 of 16 1. introduction this miniaturized 25m m square ceramic patch antenna is mounted via pin and double - sided adhesive and is the optimal embedded antenna solution for mobile globalstar applications. the antenna is tuned to a reference 60mm sq uare gro und - plane. with a peak gain of 4 dbi, the antenn a exhibits excellent upper hemispher e radiation pattern stability. a xial ratio is less than 3 on antenna operational angles, with a minimum axial ratio of 0.54 at zenith . the sp.1615.25.4.a.02 gain and directivity characteristics have been analyzed and app roved by globalstar. different device ground - planes and housing environments may require a custom tuned antenna. taoglas provides testing and support services to characterize this antenna in your device and determine whether a custom tuned solution is ne cessary. there is a minimum order quantity and possible nre for a custom solution. contact your regional taoglas office for support. spe - 14 - 8 - 104/ b /ss page 3 of 16 2. specification table parameter specification note s range of receiving frequency 1 615.68 4.1 mhz center frequency 1 61 5 mhz 3 mhz with 6 0 6 0mm gnd plane bandwidth 26 mhz min return loss@ - 10 db vswr 1.5 max center frequency gain at zenith 4 dbi typ. polarization lhcp left hand circular polarization axial ratio 3 max. @ zenith impedance 50 ohm weight 5g fr equency temperature coefficient f - 40c to +105 c 0 20ppm / c operating temperature - 40c to +105c spe - 14 - 8 - 104/ b /ss page 4 of 16 3. electrical specifications 3 .1 return loss spe - 14 - 8 - 104/ b /ss page 5 of 16 3 . 2 smith chart spe - 14 - 8 - 104/ b /ss page 6 of 16 3 .3 v swr spe - 14 - 8 - 104/ b /ss page 7 of 16 3 . 4 efficiency 3. 5 peak gain spe - 14 - 8 - 104/ b /ss page 8 of 16 3.6 radiation pattern th e antenna was test in a ceritified ets anochoic chamber, the setup is as below, y x z spe - 14 - 8 - 104/ b /ss page 9 of 16 3 . 4 .1 xz - plane 3.4.2 yz - plane z z x y spe - 14 - 8 - 104/ b /ss page 10 of 16 3. 4 . 3 xy - plane y x spe - 14 - 8 - 104/ b /ss page 11 of 16 3 . 5 axial ratio spe - 14 - 8 - 104/ b /ss page 12 of 16 4 . mechanical drawing 4.1 antenna spe - 14 - 8 - 104/ b /ss page 13 of 16 4 .2 spd.25a evaluation board spe - 14 - 8 - 104/ b /ss page 14 of 16 4 .3 pcb footprin t recommendation spe - 14 - 8 - 104/ b /ss page 15 of 16 5 . packaging 50 pieces per tray 200 pieces per inner carton 800 pieces per outer carton spe - 14 - 8 - 104/ b /ss page 16 of 16 |
