Abstract: Ever since the birth of IoT (Internet of Things) into technology, there is a widespread bloom in geo-location applications. From satellite communication to wireless sensor network developments, there is a need for location identification. This demands a low power, interference free, efficient system for multi-purpose applications. This paper focuses on the design of a Dual Band Multiple Input Multiple Output (MIMO) Antenna System for Long Range (LoRa) band at 915 MHz and GPS (Global Positioning System) at 1.57 GHz. The return loss of -20 dB and-28 dB is obtained for the desired frequency. The main objection of the paper is isolation between the antennas for two different applications mentioned above. The isolation of -15 dB to -68 dB values is achieved between various port both in simulated and measured results for both the wireless applications.
Keyword: Isolation, Multiple-Input Multiple-Output, Radiation Pattern, Return Loss.
