Combining a reflectarray and a transmitarray together, a novel array antenna with
bidirectional high-gain beams is proposed in this paper. A novel single-layer metalonly …

This article presents a wideband bidirectional same‐sense circularly polarized (CP) antenna
based on metasurface structure. The antenna consists of a rectangular slot and two identical …

A compact multilayer antenna enabled with anisotropic linear-to-circular (LTC) polarization
converter (PC) is investigated in this letter for triple-band circularly polarized (CP) operation …

This paper presents the design of a bidirectional same-sense circularly polarized (CP)
antenna that uses metasurfaces. The antenna consists of two metasurfaces, each …

ABSTRACT A circularly polarized Y‐shaped monopole antenna with L‐shaped slot loaded
ground‐plane is proposed in this letter. The multi‐band operation is achieved due to the …

A single-layer bidirectional antenna that provides circularly polarized (CP) radiation of the
same sense in both of the hemispheres has been designed and evaluated. The concept is …

This paper presents a nonresonant polarization selective surface (PSS) to address the
problem of multipath distortion in global navigation satellite system (GNSS) antennas. The …

A wideband circularly polarized antenna with L-shaped monopole slots and rotated parasitic
patches has been proposed. The measured results show that the antenna has VSWR (<; 2) …

In this paper, a wideband bidirectional endfire circularly polarized (CP) antenna is proposed
by combining two endfire CP antennas with a single coaxial probe feed. The wideband …

In this letter, a dual‐patch antenna with bidirectional circular polarization of the same sense
is proposed for coal mine and tunnel communications and positioning systems. The …
