Development of 5.8 GHz SWR Meter for Testing Telecommunication Systems

This article presents the development of 5.8 GHz SWR meter for testing telecommunication system and applying in the teaching of telecommunication engineering. The hardware based on Arduino microcontroller consists of two parts including the multi-frequency oscillator and the digital SWR meter using a directional coupler of 5.8 GHz operating frequency. The research results shown that the quality of developed SWR meter evaluated by expert is at high level. After testing the accuracy, it can be seen that the developed SWR meter has not exceed ±5 % of error in comparing to standard instrument. The developed SWR meter can be used in testing the telecommunication system and can be as an instructional aid for telecommunication engineering education as efficiently.
