Abstract
The high precision (centimetre accuracy) positioning systems are set to play a key role in revolutionising smart farming, self-driving cars, drone deliveries, heavy machine navigation, etc. With so much at stake the technology also needs protection from an intentional sabotage or denial of service. It is very easy with current satellite-based navigation jammers to disrupt a navigation service. Our proposed technology solves this challenge in a compact and cost-effective way. Compared to normal navigation patch antennas our proposed dual ring antenna offers over 30 dB of protection. Thus, if a patch antenna-based navigation system is disturbed at 1 watt of interference power, it will take 1000 watts to disrupt navigation system working on our proposed system. With the size of only 130 mm × 130 mm and cheap large-scale manufacturing, our proposed antenna is perfectly suitable for applications for safety and prosperity of the smart nation-based living.
