A compact broadband antenna for ultra high frequency and L band on 5G new radio base stations
IET Microwaves, Antennas & Propagation, 2023 A simple method is proposed for the realisation of compact dual‐polarised antennas. The aperture area of a dual‐polarised dipole antenna can be reduced by half by surrounding the antenna with a square loop.

Dual‐loop antennas with an expanded axial ratio bandwidth
Electronics Letters, 2023 The authors propose a novel dual‐wire antenna with a balanced feed to increase a 3‐dB axial ratio bandwidth. The antenna comprises loop elements with quasi two‐sources, and the effects of the element distance on the axial ratio bandwidth are revealed ...

Radio-transparent dipole antenna based on a metasurface cloak
Nature Communications, 2022 The authors demonstrate broadband and efficient radio-transparent antennas based on cloaking technology. Their features are well suited for modern communication systems, as closely spaced antennas need to be integrated with minimal interference.

Antenna Arrays Focused on Broadband Signals
Journal of Telecommunications and Information Technology, 2016 Broadband and ultra-wideband signals are increasingly used in modern radio systems. Traditional performance of evaluation antennas operating with narrowband signals are not always adequately reflect the characteristics of broadband antennas, at least in
