A new UWB-principle for sensor-array application

The paper presents a simple principle to measure the transfer function or rather the impulse response of ultrawideband systems. The main aspects of the new measurement head are its flexibility of application, its measurement speed and the possibility of a full circuit integration, which results in small, robust, lightweight and low cost devices with low power consumption. Beside this, the method allows the measurement of multi-port devices and it has a good suppression of perturbation signals. These advantages may be exploited in a great variety of microwave sensing applications, covering single sensor and array arrangements
