The Joymax GRD-C016SMDB antenna is an embedded, surface-mount, PCB substrate monopole chip antenna designed for use in Sub-1 GHz 868MHz and 915MHz frequency bands supporting low-power, wide-area (LPWA) applications such as LoRaWAN® , Sigfox® , Wi-SUN®, Weightless-P™, and WiFi HaLow™ as well as ISM unlicensed application in 868 & 915MHz frequency range.
The board-attached chip antenna provides omnidirectional radiation which perfectly matches a portable device, and features compact package and low profile to be directly mounted on the main PCB of end-users device. Connection is made to the radio through microstrip transmission lines.
