Analisis Perancangan Antena Helix Mode Axial Dan Patch Meanderline Menggunakan Dgs (Defected Ground Structure) Untuk Aplikasi Lpwan (Low Power Wide Area Networks) Berbasis Iot Pada Daerah Rural

Abstract

Due to the importance of global awareness and the government's agenda to provide digital services for rural area residents in improving signal quality, LPWAN (Low Power Wide Area Networks) applications are a major concern in infrastructure. Rural are areas that have poor quality signal, the cause lies in the location of rural areas away from the coverage area BTS so that the need for telecommunications equipment in the form of GSM repeaters. In GSM repeater devices require an antenna that has a large gain mainly on the receiving antenna, one antenna that has a large gain character is helix axial mode has a large dimension resembling a spring and has a directional radiation pattern properties, whereas the antenna with an omnidirectional radiation pattern is a patch meanderline antenna has compact dimensions and is easy to fabricate. The meanderline patch antenna has the disadvantage one of which is the small gain caused by trapped surface waves on the ground, so it needs special techniques to overcome the problem. This research will discuss the design and realization of helix axial mode and patch meanderline DGS (Defected Ground Structure) for LPWAN (Low Power Wide Area Networks) application in rural area so it can be used for IoT based weather monitoring. In the process of integrating antenna helix axial mode as receiving antenna and antenna patch meanderline DGS as rebroadcast antenna in GSM repeater able to make edge network in rural area become HSPA + network.
