Concept of Microwave Electronic Steered Array using Analogue FIR-Filter
A concept for wideband electronic steered array using analogue FIR-filters has been formulated. This paper focuses on microwave applications, e.g. wideband antenna radiation pattern, where we explain the design of a desired radiation pattern for bandwidth 2:1. Therefore we consider a linear narrowband radiation pattern and expand it to a wideband array synthesis. The requirements for higher bandwidth, e.g. 3:1 in ultra wideband (UWB) communication systems, w.r.t. different design parameters are obtained. Finally, we propose the requirements for practical realization at microwave signal level.
