Abstract
This paper focuses on the design of a planar 4×4 butler matrix functioning at 2.45 GHz band frequency. The purpose is to exploit this matrix as a beam forming network generating orthogonal beams oriented towards various directions. For that, we have implemented a simple microstrip structure with single layer. We have also integrated some microwave devices, namely phase-shifters, 3 dB couplers and cross-couplers.
