A novel wideband low-profile planar antenna design based on the use of a high-impedance
surface (HIS) is presented for digital television (DTV) reception in the UHF band. The …

This paper presents a very compact, wideband, and enhanced-gain antenna for 5G
applications. A simple single-layer millimeter wave (mm-wave) metamaterial lens (meta …

In this article, a new low‐profile broadband circularly polarized antenna with a single‐layer
metasurface is designed. The metasurface is composed of 4× 4 rotated rectangle‐loops …

A low profile dual-circularly polarized printed ring-slot antenna with a small footprint, which
radiates above an open cavity loaded with an artificial magnetic conducting reflector, is …

A metamaterial loaded circularly polarized fractal boundary patch antenna is investigated for
applications at the ISM band. The suggested patch comprises of Minkowski fractal over …

A novel broadband circularly polarized (CP) squarering-loaded slot antenna with flat gains
is proposed in this letter. The antenna is fed by an L-shaped microstrip line with tapered …

A technique to design a wideband circularly polarized (CP) cavity-backed aperture antenna
is presented in this letter. The proposed antenna consists of an aperture antenna, a low …

This paper presents a high efficiency and low profile quad‐beam circularly polarised
transmitarray antenna using metasurface. In order to improve the aperture efficiency, the …

Two wideband circularly polarized (CP) antenna arrays are proposed, based on sequential
rotation (SQR) arranged polarization grid and specially designed wideband full-substrate …

This paper presents a novel differentially driven planar aperture antenna with circularly
polarized (CP) radiation. The proposed antenna is simple in structure yet can achieve high …
