The Joymax PLF-C025MP4B antenna is an embedded, RHCP, Stacked Ceramic Patch antenna integrated with 2-stage LNA designed for use in 1176.45 MHz, 1127.6 MHz and 1559~1608 MHz frequency bands supporting Global Navigation Satellite System (GNSS) including GPS (L1, L2, L5), GALILEO (E1, E5a), GLONASS (G1), BeiDou/Compass (B1, B1C, B2a), QZSS (L1, L5) and IRNSS (NavIC) for Navigation, Location, Timing applications.
The embedded antenna has a coax cable terminated in a MHF1/UMCC/U.FL Plug connector. The antenna may be mounted inside end-user device enclosure by mechanical means e.g. bracket, adhesive (not included), alternatively soldering LNA shielding case to the main PCB.
