Description

Manufacturers & Contacts

  • Raltronis offering a wide selection of antennas ranging in frequency from 433 MHz to 5.9 GHz. Raltron has Chip, NFC, FPA, Metal, PCB, Patch, Stub, Dipole, Helix, Ceiling and Wall Mount solutions. Applications include Bluetooth, Wi-Fi, ZigBee, Lora, Sigfox, GPS / GLONASS / BeiDou, automotive navigation, cell phones, wireless and RFID systems.Raltron offers GPS Patch antennas in three different configurations –passive patch, active external patch, and active internal patch; they vary in sizes from 9 x 9 mm to 49 x 39 mm. Additionally we offer dual band GPS/GLONASS passive patch antennas in 13 x 13 mm, 25 x 25 mm and 49 x 39 mm dimensions. Raltron’s chip antennas can operate in the 1.575 GHz Band, 2.5 to 3.8 GHz (WiMAX Frequencies) and either single or dual bands for 2.400 to 2.485 GHz and/or 4.9 to 5.9 GHz (Bluetooth/Wi-Fi) . The small size of these chip antennas from 3.2 x 1.6 mm to 10.0 x 3.2 mm, along with omni-directional radiation patterns and peak gain to 4 dBi, offers the best conversions from cost, size and performance stand point. The ultra-thin flexible antenna structure of out NFC series allows for peel and stick antenna designs for a variety of applications such as NFC payment readers, health care ID scanners and ticketing systems.
