spe - 11 - 8 - 098 /d/ss page 2 of 9 1. introduction this 18mm ceramic gps /glonass patch antenna , by means of a double resonance design, has unique wide - band operation over the whole operating bands of gps and glonass systems from 1575mhz to 1610mhz. the antenna achieves best in class right hand circularly polarized gain with good axial ratio characteristics mitigating multi - path effects which is vital to improved s/n carrier ratio and faster locking times on the device itself . it is mounted vi a pin and d ouble - sided adhesive . this antenna has been tuned for a centre position on a 70 mm*7 0 mm ground - plane. it is manufactured and tested in a ts16949 first tier automotive approved facility. for further optimization to customer specific device environments whe re positioning is off centre or on different ground - plane sizes, custom tuned patch antennas can be supplied. for more details please email sales@taoglas.com 2. specification electrical range of receiving frequency gp s: 1575.42 1.023mhz glonass: 1602 5mhz center frequency 15 92 mhz 3mhz vswr 2.4 max gain at zenith + 3 .0 dbic typ. polarization rhcp impedance 50 ohms mechanical ceramic dimension 18 mm x 18 mm x 4mm pin diam eter 0.9mm pin length 1.8mm environmental operation temperature - 40c to 85 c humidity non - condensing 65c 95% rh * antenna properties were measurement with the antenna mounted on 70 *7 0 mm ground plane
