This paper presents a general overview of substrate integrated transmission lines, from the
perspective of historical background and progress of guided-wave structures and their …

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

With the demanding system requirements for the fifth-generation (5G) wireless
communications and the severe spectrum shortage at conventional cellular frequencies …

A planar millimeter-wave 2-D beam-scanning multibeam array antenna fed by compact 16-
way beamforming network (BFN) in multilayered substrate integrated waveguide (SIW) …

This communication presents the design of a wideband circularly polarized (CP) multibeam
transmitarray with a cluster of linearly polarized (LP) feeds for millimeter-wave applications …

The goal of this paper is to propose a new antenna array architecture that aims to solve the
most known limitations of phased antenna arrays, resulting a good candidate for next 5G …

A wideband dual-layer Huygens' unit cell based on offset electric dipole pair (OEDP) is
proposed. Different from traditional designs with a combination of electric and magnetic …

A novel methodology is introduced for designing bespoke homogeneous and graded index
lenses for enhancing the gain of travelling wave antenna arrays (TWAs). 3D-printed lenses …

In this article, a dual-polarized multibeam antenna is proposed. Two orthogonally polarized
slotted waveguide antennas (SWAs) are cross-placed as the main radiator, which is …

A compact wideband wide-angle polarization-free metasurface lens (MSL) antenna array is
proposed for a multibeam base station operating over the band of 1.71-2.2 GHz. The MSL …
