Latona Antennas for LP-WAN Applications Antenova M2M Latona Antennas for LP-WAN Applications use a ground plane on the host PCB to radiate effectively. The antenna requires a clearance underneath, while an external matching circuit is used to optimize the antenna to the required bands within a device. Available in left and right-hand versions to optimize placement, the Latona antennas are designed specifically for LP-WAN applications that require a small, robust solution. Typical applications include remote monitoring/smart meters, network devices, smart buildings, smart cities, manufacturing automation, agriculture/environment, and consumer tracking applications.
