A new polarization diversity converter (PDC) is presented in this paper based on a multilayer frequency selective surface (MFSS). The MFSS consists of three-layer square patches with truncated corners and two-layer grid lines. The converter is considered as a free-rotating screen. The polarization of the transmitted wave can be reconfigured to linear polarization or circular polarization by rotating...
A circular polarized Fabry-Perot resonator antenna for dedicated short range communication(DSRC) is presented in this paper, the superstrate of which has the FSS structure with square elements. The antenna is designed to meet the physical layer protocol of Chinese National standard GB/T 20851-2007. The full-wave simulation results obtained by Ansys HFSS show that the proposed Fabry-Perot antenna has...
In this paper, a single-layer bandpass frequency selective surface (FSS) is proposed for L-band applications. The FSS unit cell consists of an improved hexagonal aperture unit embedded with H-shape slots. Simulated results show that the FSS obtains good frequency selective performance. Its relative bandwidth is about 55.7% using −3 dB as the criteria for the transmission coefficient. Moreover, the...
A new design of a dual-band shared-aperture antenna based on frequency selective surface (FSS) for synthetic aperture radar (SAR) applications is presented. Bow-tie patches are used as the radiating elements both at L-band and C-band. The centre frequency of the L-band antenna is 1.3 GHz and the centre frequency of the C-band antenna is 5.2 GHz. The simulated impedance bandwidth (S11 ≤ −10dB) of the...
