Abstract
A simple dual wideband shared-aperture antenna array with wide 2-D angle scanning is proposed in this letter. One printed dipole antenna element operating in X band and four microstrip quasi-Yagi antenna elements operating in Ku band are combined to construct a shared-aperture supercell for the phased array. Gaps are cut on the substrate to reduce the mutual coupling between the adjacent elements. Both the X band and Ku band elements are printed on one-layer substrate to realize dual wide bands with the same polarization, meanwhile exhibiting a simple structure. A large array topology composed of 14 × 12 X band units and 16 × 16 Ku band units is fabricated for verification. Measured results show that the proposed antenna array has wide bandwidths of 11.8% in the X band and 25% in Ku band, meanwhile it has a relatively wide scanning angle ranging from −60° to +60° with the gain decrease less than 5.1 dB.
期刊介绍：
IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
