In this review paper, a comprehensive study on the concept, theory, and applications of
composite right/left-handed transmission lines (CRLH-TLs) by considering their use in …

While 5G is tasked to transform our lives for the better over the next 10 years, next-
generation mobile communications, aka 6G, will undoubtedly demand even higher energy …

The progress of technology in consumer electronics demand an antenna having a compact
size, high gain and bandwidth, and multiple antennas at transmitter and receiver to enhance …

With massive deployment, multiple-input–multiple-output (MIMO) systems continue to take
mobile communications to new heights, but the ever-increasing demands mean that there is …

This paper presents the results of a study on improving the performance parameters such as
the impedance bandwidth, radiation gain and efficiency, as well as suppressing substrate …

Fluid antennas embrace all forms of flexible-position antennas, both movable and non-
movable. Hence the concept of fluid antenna system (FAS) introduces a new dimension to …

This letter presents a novel broadband microstrip patch antenna with a simple geometry.
Two parasitic mushroom-type arrays are incorporated along with the two radiating edges of …

Optical metamaterials are artificially engineered architectures that exhibit desired optical
properties not found in nature. Bespoke design requires the ability to define shape, size …

A novel miniaturized, aperture-shared, vertically polarized (VP), zeroth-order resonance
