The Latona is a compact chip antenna for LP-WAN applications including NB-IoT, LoRa, SigFox, ISM and Weightless-P where a small robust antenna is needed. It operates from 791 to 960 MHz with linear polarizsation and a peak gain of 0.8 dBi with an efficiency greater than 60%. The antenna is matched to 50 ohms and measures 20.0 x 11.0 x 1.6 mm.
The antenna uses a ground plane on the host PCB to radiate effectively. The antenna itself requires a clearance underneath. An external matching circuit is used to optimise the antenna within a device to the required bands. It has an innovative space saving design with left and right options thatenable it to be placed on a corner.
