IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.A millimetre‐wave tilting beam‐steering substrate‐integrated waveguide (SIW) horn antenna is proposed for millimetre‐wave communications. The measured results indicate that an impedance bandwidth below |S_{11}| < −10 dB from 25.60 to 27.72 GHz, with a peak gain of 10.5 dBi and a front‐to‐back ratio (FTBR) exceeding 15 dB.

International Journal of Electronics and Telecommunications, 2017 Abstract In this paper, the substrate integrated waveguide (SIW) resonator is designed to study the influence of dielectric materials on its operating parameters (insertion loss, fractional bandwidth and unloaded Q-factor). The results obtained show that the use of high permittivity substrate in the SIW resonator by increasing its thickness allows

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.We introduce a simple approach to taper the amplitude distribution in leaky‐wave antennas by exploiting a nonradiative dielectric waveguide topology. By shaping the dielectric section, the longitudinal attenuation constant and therefore the amplitude distribution can be easily controlled to lower side lobe levels.

Uniform Circular Array Antenna for Dual‐Mode Orbital Angular Momentum Generation at 6 GHz
International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.Orbital angular momentum (OAM) antennas have recently attracted attention for their potential to enhance communication capacity and and robustness against interference. However, most existing designs rely on complex multilayer feed structures. This work presents a compact, single‐layer, series‐fed dual‐mode OAM antenna composed of four patches arranged
