Leading Edge Conformal ARMA Antenna in X Band

This paper presents a multi-source conformal antenna using ARMA (Agile Radiating Matrix Antenna) principle. This antenna has the shape of an airplane wing leading edge. It performs radar or communication application in X band. A technique using a commercial software to compute the phase shift of excitations is proposed. It compensates antenna curve to obtain a radiation pattern with a directivity in the axial direction of 20 dB near the equivalent planar antenna. Side lobe levels are below -13 dB. Moreover, the antenna provides beam steering using a phase law.
