| description | In this paper, an ultra-wideband tightly couple antenna array based on a low-loss phase-modulated frequency selective surface and a microstrip-based feeding structure is reported. The proposed antenna array, which employs tightly coupled bow-tie elements, features a very low profile (1.08<inline-formula> <tex-math notation="LaTeX">$\lambda _{high}$ </tex-math></inline-formula>). Specifically, a microstrip-to-parallel strip transition serves as an impedance transformer and a wideband balun to enable the array element to be excited with a 50 <inline-formula> <tex-math notation="LaTeX">$\Omega $ </tex-math></inline-formula> unbalanced feeding scheme. Additionally, one shorting sheet is employed to expand the bandwidth by shifting the common-mode to a higher frequency band. The presented design achieves a bandwidth of 13.66:1 (0.52 GHz – 7.10 GHz) with VSWR < 2.49 and simulated radiation efficiency greater than 96% across the whole band. To validate the design concepts, an <inline-formula> <tex-math notation="LaTeX">$8\times8$ </tex-math></inline-formula> array prototype is fabricated and characterized experimentally. The measured results match well with the numerical analysis. |
