The radome has minimal impact, and outdoor/indoor tests yield power measurements at 514 MHz of 38.4 dB\(\mu\)V (\(-\)70.4 dBm) and 26.6 dB\(\mu\)V (\(-\)82.2 dBm), with carrier-to-noise ratios (C/N) of 11.6 dB and 10.9 dB. Boasting a compact size of 30 \(\times\) 18 \(\times\) 1.6 mm\({}^{3}\), the ultra-wideband (UWB) multiple-input, multiple-output (MIMO) antenna by [PERSON] et al. (contribution 26) exhibits flower-shaped radiating components, providing high isolation and excellent performance across the entire operation band of 4.3-15.63 GHz. The proposed design holds promise for diverse UWB applications. In contribution 27, by [PERSON] et al., a dual-band wearable patch antenna with split-ring resonator (SRR)- and electromagnetic bandgap (EBG)-based designs is presented. The SRR-based antenna demonstrates improved gain, surface wave suppression, and compactness, showcasing its potential for wearable sensor networks and IoT applications. Contribution 28 by [PERSON] et al. introduces a dual-band high-gain shared-aperture antenna that integrates Fabry-Perot and reflect-array mechanisms. Operating in both the S-band and X-band, the antenna achieves impressive gains with good isolation between the two frequency bands, making it an attractive candidate for high-performance communication systems. The paper by [PERSON] et al. (contribution 29) introduces polarisation-reconfigurable patch antennas using semiconductor-distributed doped areas (ScDDAs). The co-design method presented enables the optimisation of both the antenna and the ScDDAs, offering a practical and efficient solution for polarisation reconfiguration. Contribution 30 by [PERSON] et al. addresses the growing importance of electromechanical coupling in high-frequency communication base station antennas. The authors establish a comprehensive channel capacity model, considering factors like positional shift, attitude deflection, and temperature change, providing insights crucial for the design and manufacture of advanced communication systems. The research by [PERSON] et al. (contribution 31) introduces a novel metasurface comprising complementary units, enabling multi-band dual polarisation conversion. The design not only achieves remarkable frequency bands for linear and linear-to-circular polarisation conversion, but also shows radar cross-section (RCS) reduction capabilities, extending its application to multiple microwave frequency bands. In the realm of 5G communication systems, [PERSON] and team (contribution 32) present a dual-band metamaterial-based absorber operating at 24 GHz and 28 GHz. Addressing the challenges of massive MIMO techniques, their absorber design enhances gain and spatial multiplexing while effectively isolating adjacent antennas. This innovative absorber holds promise for compact 5G devices by preventing unwanted interactions between antennas. [PERSON] and colleagues (contribution 33) contribute a unique feeding method for linear dielectric resonator antenna (DRA) arrays. By utilising standing waves and discrete metallic patches, the authors achieve a high-gain DRA array with low losses, presenting a cost-effective and compact design. The proposed 3D-printed structure demonstrates high efficiency, making it a noteworthy advancement in feeding techniques. In contribution 34, [PERSON] et al. present a low-profile wideband magnetoelectric (ME) dipole antenna. The design involves the intricate bending of structures to achieve a reduced antenna height, while maintaining wideband properties. The relative bandwidth for VSWR \(<\) 2.0 and low boresight gain drop make this antenna suitable for applications requiring limited height and wideband characteristics. [PERSON] et al. (contribution 35) propose a filtering slot antenna using characteristic mode analysis (CMA). Their approach involves analysing and designing characteristic magnetic currents to achieve a wide filtering bandwidth with stable gain.
