Abstract

LoRa is a type of Low Power Wide Area Networks (LPWANs) using low energy, which is important for internet of things technology that transfers data with low data rate and uses low energy for long distance transmission in the area without the use of internet signals or mobile phone networks. Thus, expanding of an area coverage by increasing antenna gain is significant. This research proposes the design and simulation of Yagi-Uda switched beam array antenna in the 920 MHz frequency band in order to enhance antenna gain compared to general LoRa antennas. Criteria of antenna design and simulation are orderly described according to the practical principle. As shown in the results, when increasing the number of elements in Yagi-Uda antenna and arranging Yagi-Uda antennas in the array form, the antenna gain can be increased and the longer distance transmission on the LoRa networks can be achieved. Meanwhile, beam steering can be performed by adjusting phases of signals.
