Abstract

Sewage systems are being retrofit with sensor networks to reduce their deleterious effects on human health and the environment. To implement the sensor networks a conventional cast-iron manhole cover is replaced with a robust composite manhole cover antenna. The difficulties in designing the antenna in a manhole cover are that the antenna must radiate in a harsh environment, at ground level, and maintain low-profile. The cover must maintain structural loads as large as 2,000 pounds, due to the presence of traffic, while simultaneously being relatively *transparent* for RF radiation from below ground sensors. To verify a prototype, a simple composite sandwich structure is designed, fabricated, and integrated with an aluminum slot antenna. This composite manhole cover antenna is analyzed with full-wave simulations and measured in an anechoic chamber. The simulated results show a good agreement with measured results. The magnetically center-fed slot antenna shows 2.13 dB of measured gain within the fiberglass sandwich structure.
