摘要：
In this letter, a planar array antenna with multiple-beams in orthogonal planes is proposed and investigated. A shared aperture is deployed for achieving a compact size, which is based on a cross transmitting network consisting of the substrate integrated waveguide (SIW) and the stripline. Two 1-D passive beamforming networks (BFNs) consisting of folded SIW Cassegrain reflectors are designed and integrated independently with the shared aperture. For demonstration, an 8 x 8 slot array at 26.0 GHz is designed and measured. In orthogonal planes, i.e., the xz plane and yz plane, six radiation beams have been achieved within +/- 40 degrees, respectively. The proposed antenna is a good candidate for the millimeter-wave fifth-generation (5G) wireless applications.
