Magneto-Electric Dipole Antenna Arrays [PDF]

open access: yesIEEE Transactions on Antennas and Propagation, 2014
A planar magneto-electric (ME) dipole antenna array is proposed and demonstrated by both full-wave analysis and experiments. The proposed structure leverages the infinite wavelength propagation characteristic of composite right/left-handed (CRLH ...

A compact broadband antenna for ultra high frequency and L band on 5G new radio base stations

open access: yesIET 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.

Miniaturization of a Koch-Type Fractal Antenna for Wi-Fi Applications

open access: yesFractal and Fractional, 2020
Koch-type wire dipole antennas are considered herein. In the case of a first-order prefractal, such antennas differ from a Koch-type dipole by the position of the central vertex of the dipole arm.

Miniaturized Spoof Plasmonic Antennas with Good Impedance Matching

open access: yesNanomaterials, 2022
The ability of spoof surface plasmon polaritons (SSPPs) to confine electromagnetic fields in a subwavelength regime enables the design of miniaturized antennas. However, the impedance matching scheme for miniaturized spoof plasmonic antennas has not been
