As mobile networks evolve towards 5G and beyond, higher data rates and the use of higher-frequency bands are becoming essential. However, these advancements face challenges, particularly with radio signal blockages that reduce network reliability. This thesis explores groundbreaking solutions aimed at improving the electromagnetic performance of mobile communication systems through novel antenna technologies integrated into building infrastructure and antenna-user interaction modeling. 

The thesis introduces the concept of signal-transmissive walls, where embedded antenna elements enhance signal penetration in load-bearing walls without compromising structural integrity. Additionally, it presents the first-ever millimeter wave compatible human body phantoms, enabling accurate and repeatable assessments of antenna-human interaction in mobile devices. These innovations pave the way for optimizing communication systems and improving user experiences in future 5G and beyond networks.

Keywords: Antenna-embedded walls, Multi-physical analysis, Antenna-user interaction, millimeter-waves
