Measuring the quality of human health and wellbeing is one of the key growth areas in our society. Preferably, these measurements are done as unobtrusive as possible. These sensoric devices are then to be integrated directly on the human body as a patch or integrated into garments. This requires the devices to be very thin, flexible and sometimes even(More)
This paper presents a simple and accurate model for the multilayer microstrip, which can be easily implemented using closed-form microstrip design formulas. The model is based on two similar approximations that reduce the multilayer substrate to an equivalent single-layer structure. The shunt impedance parameters per unit length are derived from the complex(More)
