Abstract
In this paper, a novel design of sensor-antenna is proposed. The approach consists on integration a capacitive sensor in a very narrowband triangular antenna that can send raw information through the antenna’s resonant frequency. As a result, we obtain a corresponding table between the resonant frequency of the sensor-antenna and the measured physical parameter. The simulated results of the designed sensor-antenna will be presented and discussed. The simulation results are promising and show that the use of the proposed sensor-antenna can be a good alternative for low energy consumption and low cost wireless sensor node.
