Summary: This article presents a dual-band dual-polarized antenna with frequency selective surface (FSS) that is compact in size and has high gain. The proposed antenna design allows radiation from the high-band element to transmit through the FSS-radiator of the low-band element, resulting in improved gain without reducing the gain of the high-band element. A prototype of the antenna operating in the 2.3-2.7 GHz and 3.3-3.8 GHz frequency bands was fabricated and measured, demonstrating high gain in a compact radiation aperture. The proposed antenna is suitable for multiband aperture-shared arrays due to its easy fabrication and low cost.

Summary: This paper proposes a novel metasurface (MS) and a generalized dual-circular-polarized (CP) decoupled modulating method. The MS can achieve high-efficiency dual-spin transmissions with equal-magnitude under left-handed circular polarization (LCP) incidence across 9-12.5 GHz. By rotating the receiver and transmitter patches separately, totally decoupled and dispersion-less phase modulations for transmitted dual-spin waves can be obtained. The proposed wideband and high-gain dual-CP multi-beam transmitarray antennas (TAs) have promising prospects for various applications.

Summary: In this article, a linearly polarized (LP) printed dipole antenna (PDA) combined with a transmissive-type frequency selective surface (FSS) is proposed. The FSS converts LP waves to circularly polarized (CP) waves with two frequency bands. The LP dual-band PDA overlaps with the operating frequencies of the FSS converter, resulting in two fractional impedance bandwidths and measured gains of around 6.23 dBi and 6.51 dBi.
