A Wide Scanning Method for a Flexible Conformal Antenna Array with Mutual Coupling Effects

This letter presents a pattern synthesis method for flexible conformal array antenna with wide scanning angle and mutual coupling considerations. The array consists of two sectors that are conformed to a circular arcs with deformable surface. The optimal element excitations are obtained by second order cone programming. The proposed method gives a flexibility in an array shape that can be deformed by tuning the folding angle. Furthermore, the effectiveness of the proposed method is verified by numerical results.
