Abstract

In a sensor on the basis of surface wave components disposed in a housing with at least one surface wave component, a fluid channel and conductors for high frequency signals, the conductors are connected to coupling capacitors with capacitive coupling surface areas which are arranged opposite each other on the housing and the surface wave equipment and closely adjacent one another so that high frequency signals can be transmitted to, and from, the surface wave components.
