Abstract
In this paper, system requirements to implement efficient underground IoT systems are overviewed, and novel manhole-cover shaped antenna is proposed. To verify its performance, the antenna prototype is designed for 900MHz-band operation, and it provides an omni-directional radiation pattern for reaching wide coverage.
