Filter Design Using Ultra‐Miniaturised Substrate‐Integrated Coaxial Cavity

IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.
The proposed substrate‐integrated coaxial cavity (SICC) comprises two dielectric substrates with three metal layers. The top and bottom metal layers form the cavity's broadside walls, and the middle is a circular patch that shorts to the bottom wall and to an embedded split CPW ring, respectively, through a blind‐via ring and three blind vias.

Cross‐Polarisation Suppression in Self‐Diplexing Antennas

IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.
An approach to improve cross‐polarisation (XP) radiation in probe‐fed microstrip antennas is presented in this letter. The notable XP associated with self‐diplexing antennas caused by radiator multiplexing is discussed for the first time. In order to enhance the interport isolation and polarisation purity, the proposed antenna exploits the combined ...

Realisation of an E‐Plane Metal‐Insert Filter at E‐Band Based on Multi‐Layer Waveguide With Pin Array Electromagnetic Band Gap

IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.
A multi‐layer waveguide (MLW) bandpass filter is realised by stacking thin metal layers at E‐band. ABSTRACT In this paper, a multi‐layer waveguide (MLW) bandpass filter is realised by stacking thin metal layers at E‐band. In order to eliminate the leakage between layers, an electromagnetic band gap (EBG) pin array is utilised.

Design of SIW‐Based Compact and High‐Gain Filtenna Array for W‐Band

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2025, Issue 1, 2025.
This paper proposes a compact and high‐gain filtenna array based on substrate‐integrated waveguide (SIW) technology for the W‐band (75–110 GHz) high‐speed wireless communication systems and imaging/detection systems. By utilizing the high integration of SIW technology, the SIW filter, butterfly slot antenna array, and patch antenna array are vertically

A Super‐Ionic Solid‐State Block Copolymer Electrolyte

Small, Volume 20, Issue 49, December 5, 2024.
The super‐stoichiometric addition of LiTFSI to poly(ethylene oxide) block copolymers leads to super‐ionic solid polymer electrolyte membranes reaching exceptionally high ion conductivities of up to 0.04 S cm−1 at room temperature, with activation energies of only 0.19 eV.

Time transfer via single‐record TDoA measurements of GNSS satellites using direct cross‐correlation and relative pilot code phases

IET Radar, Sonar &Navigation, Volume 18, Issue 12, Page 2447-2453, December 2024.
A method is presented to passively synchronise data records via GNSS raw signals in a single record requiring only a GNSS antenna, an analogue‐to‐digital converter and computation hardware. The clock bias is estimated via the common view method with either full raw signal correlation or software‐based code correlation of individual signals from the GPS,

Integrating deep convolutional surrogate solvers and particle swarm optimization for efficient inverse design of plasmonic patch nanoantennas

Nanophotonics, Volume 13, Issue 21, Page 3963-3983, September 2024.
Abstract Plasmonic nanoantennas with suitable far‐field characteristics are of huge interest for utilization in optical wireless links, inter‐/intrachip communications, LiDARs, and photonic integrated circuits due to their exceptional modal confinement. Despite its success in shaping robust antenna design theories in radio frequency and millimeter‐wave
