A narrowband channel model (2.4 GHz to 2.5 GHz) for wireless sensors deployed over the external surfaces of a gas turbine engine is reported. The model is empirical and based on a series of transmission loss measurements over the surface of a gas turbine engine.
In this paper, the suitability of using a printed circuit board (PCB) microstrip patch receiving antenna for a novel application - RF energy harvesting to power a wireless soil sensor network deployed in an outdoor environment - is investigated. The performance of a conventional circular microstrip patch antenna using different microwave laminate substrates is evaluated in terms of return loss, radiation...
Printed monopoles are suitable radiators for sensor nodes, and straightforward enablers of compact arrays. Arrays offer the advantage of diversity, which is a true enabler of mobile sensor networks. However, compact arrays with closely spaced elements become detuned and lose bandwidth, while mutual coupling hinders diversity. Prior studies described a simple and efficient technique to reduce coupling...
