A metasurface‐based low‐profile crossed dipole antenna with wide circularly polarized
bandwidth for 2.45 GHz ISM band wireless communications is proposed and fabricated in …

This communication presents a wideband circularly polarized (CP) aperture antenna array
with a specially designed feeding network. First, an irregular-cavity-backed aperture …

The authors proposed a unidirectional, high‐gain antenna loaded with the artificial magnetic
conductor (AMC) back‐cavity, which generates the reflection phase of 0° for gain …

In this paper, a compact circularly polarized co-designed filtering annular slot antenna (ASA)
is proposed. The antenna comprises a distributed capacitor-loaded annular slot radiator to …

A polarisation independent artificial magnetic conductor (AMC) miniaturised using
interdigital capacitors is investigated. Its performance is analysed and compared with two …

This paper proposes a novel antenna design suitable for unlicensed frequency spectrum (57-
