There are many kinds of antenna for NB-IoT. Roughly, it is almost same as the LTE antenna. But, due to different application field, it has own characters. To design an antenna for NB-IoT application, you need to consider antenna’s frequency, gain, return loss, radiant efficiency, and radiation polar pattern. Grand-Tek offers variety of 5G antennas that suit for outdoor/indoor IoT applications. Additional antenna features include SMA, N Plug, N-Jack, & 2.2-4.0 dBi.
