摘要
Abstract
A reflect-transmit metasurface that can independently regulate the amplitude and phase is pro-posed.It can independently control the forward and backward beams in each of the two frequency bands.The designed MS unit consists of three metal layers separated by two substrates.The amplitude and phase of reflection and transmission are regulated by the orientation and opening angles of the upper I-shaped patch and the lower C-shaped ring patch,respectively.The polarizations of transmission and reflection are the same.Transmission mode and reflection mode are at 12.9~15.4 GHz and 18.6~26.4 GHz,respectively.The interference between the I-shape structure and the C-shape ring structure is eliminated by the intermediate slot layer,so that the transmitted beam and the reflected beam can be inde-pendently regulated and their function can be independently realized in the range of the frequency band in which it operates.On this basis,a dual-frequency multifocal super-lens is designed and the focus can be formed at the specified position,which verifies the ability of the unit amplitude-phase independent regula-tion.Finally,the reflect-transmit-array antenna of 17×17 is designed,fabricated,and measured as well as fed through a horn antenna.The measurement results show that the peak gain of the transmission array function is 19.60 dBi(1 dB gain band-width:18.69%)and the peak gain of the reflection array function is 26.60 dBi(1 dB gain bandwidth:26.98%).The proposed reflect-transmit-array antenna provides a new solution to achieve bidirectional communication over a wide bandwidth range.关键词
