Multi-beam antennas are critical components in future terrestrial and non-terrestrial wireless
communications networks. The multiple beams produced by these antennas will enable …

A double-layered Huygens' unit cell is proposed to design a broadband metasurface lens
(meta-lens) for 5G millimeter-wave antennas. The Huygens' unit cell consists of a pair of …

This article presents the designs of ultrawideband microwave flat gradient index (GRIN)
lenses, which realizes over a 108% fractional bandwidth (12-40 GHz). The frequency …

A high-efficiency conformal transmitarray with ultrathin dual-layer Huygens element is
developed. The element consists of “I” shape patches for magnetic response and “T” shape …

The use of microstrip transmitarrays (TAs) and reflectarrays (RAs) is essential in long-range
communication systems because of their high-gain radiations, narrow beam widths, simple …

A prior-knowledge-guided deep-learning-enabled (PK-DL) synthesis method is proposed for
enhancing the transmission bandwidth and phase shift range of metacells used for the …

Metasurfaces, which are planar surfaces or interfaces constructed by placing subwavelength
scatterers into a two-dimensional array pattern, have attracted much attention in recent …

This paper presents the complete design of a wideband transmit-array (TA) antenna with
high gain and high efficiency for D-band applications based on the low-temperature co-fired …

Recently, there has been growing interest in the use of metamaterial (MTM)-based lenses,
also known as metalenses, as innovative antenna technology. Increasingly widespread …

An ultrathin and low-profile metalens antenna based on chain Huygens' metasurface is
proposed for 28 GHz band applications. The metasurface consists of an array series of …
