Due to Indonesia's position in the ring of fire implies a potential disaster throughout the year, it needs to be mitigated by installing ground sensor data throughout Indonesia including in remote areas, but most places lack communication signals. The satellite-based mitigation communication system is one solution in connecting sensors and ground stations. It requires an antenna that has compact size and high performance to do the mitigation communication system. A rectangular microstrip antenna for LoRa communication in the 924 MHz frequency range for disaster mitigation is proposed to improve the performance of Lora which has low power and long-distance performance characteristics. The antenna is made with a Rogers Duroid RT6006 substrate and applies a Single Complementary Split Ring Resonator (CSRR) to increase gain and reduce antenna dimensions. Based on the simulation, the antenna return loss 16.15 dB, gain 2.2 dBi, and elliptical polarization with axial ratio 6.98 dB. Measurements show the performance of return loss 19.82 dB, gain 2.6 dBi, and an elliptical antenna with an axial ratio of 7.2 dB.
