ABSTRACT

In this paper, a novel partially reflction surface (PRS) is proposed. It is a single layer periodic array, which is composed of two folded long dipoles, two rectangular patches and four short dipoles. Two folded long dipoles are main resonant cells, which provides positive reflection coefficient phase gradient. In addition, two rectangular patches and four short dipoles can improve reflection coefficient magnitude to some extent. Compared with other papers, the novelty of this paper is that the proposed structure is single array, but the most proposed structure of other papers are dual layer periodic patch arrays. The reflection coefficient phase of this PRS increases linearly with operating frequency from 6.1GHz to 6.7GHz. The simulated results show that the reflection coefficient phase of this PRS is completely consistent with the theoretical reflection coefficient phase, the reflection coefficient magnitude of this PRS ias about 0.728 at 6.48GHz. Therefore, it can be used as superstrate of the Fabry-Perot resonator antenna for enhancing its half-power fractional bandwidth and gain.
