NB-IoT System Performance Enhancement using Directional Antenna

Nowadays NB-IoT has gained lots of attention from researcher so far as its many advantages. This paper shows an increase in NB-IoT performance when employing directional antenna. The designed microstrip antenna is fabricated for testing the NB-IoT performance in real circumstances. From experiment, the signal strength when employing the proposed antenna is higher comparing to the case of omni-directional antenna.
