摘要：
In this paper, a low-profile, light weight ultrawideband array antenna based on tightly coupled dipole antenna element is investigated. A hybrid wide-angle impedance matching (WAIM) layer consist of a parasitic dipole layer and a frequency selective surface (FSS) layer is used to replace the traditional dielectric wide-angle impedance matching layer. The parasitic dipole and FSS are printed on thin dielectric substrate laminated with PMI foam, which can effectively reduce the antenna weight. The infinite array element achieves 6:1 bandwidth with VSWR <= 3 for scanning to +/- 60 degrees in E-plane and VSWR <= 3.5 for scanning to +/- 45 degrees in H-plane. The array element profile is less than one tenth of the wavelength of lowest operating frequency.
