The growing demand for high-data-rate wireless communication systems such as 5G networks, IoT infrastructure, and millimeter-wave radar requires compact and highperformance antenna solutions. Low-Temperature Co-fired Ceramics (LTCC) technology offers a promising platform for such applications due to its multilayer architecture, electromagnetic stability, and compatibility with passive and radiating component integration.
In this context, this thesis focuses on the design, simulation, fabrication, and experimental characterization of integrated antennas implemented using LTCC technology. Two microstrip patch antennas operating at 2.45 GHz were first developed to validate the feasibility of this approach in the ISM band. These structures demonstrated a measured gain exceeding 1.6-dBi and radiation efficiency above 85%.
For higher-frequency applications, a dielectric resonator antenna (DRA) element was designed and integrated into a 2×2 antenna array with a corporate feed network, all fabricated on an LTCC substrate. This structure achieved a measured gain of 11.8 dBi and radiation efficiency above 90% in the 26–30 GHz band, meeting the performance requirements for mm-Wave communication.
This work presents a complete methodology from electromagnetic modeling to experimental validation and opens the way for future development of LTCC-based antennas in emerging wireless technologies.
