چکیده :
In this paper, a design procedure for dual-beam orthogonal circular polarized leaky-wave antenna based on the holographic technique is presented. The hologram modulated surface is composed of anisotropic unit cells with printed elliptical patches. The variations of large and small diameters and rotation angles of patches determine the required components of the tensor surface impedance to implement the hologram. An edge-fed excitation approach is utilized to produce a reference surface wave with a planar front wave. The direction of two forward and backward object waves is arbitrary selected. The polarization of forward pencil beams is considered as right-hand circularly polarized (RHCP) and the other one as left-hand circularly polarized (LHCP). The dimension of the proposed structure is about 12.5*12.5 λ02. The gain and the radiation efficiency of the proposed antenna are about 25.7 dBi and 92%, respectively. The simulations have been carried out by MATLAB and CST Microwave Studio software.
