(POSTER) Advanced LTCC-Integrated Technologies for mmWave 5G/Satellite Communication Antennas

Ultra low-loss materials, wave guiding structures and circuit fabrication technologies are critical for high performance mmWave antenna arrays destined for 5G and satellite communications. This poster presents recent advances on all three fronts through the use of: (i) ceramic materials and high conductivity silver metallization, (ii) substrate-embedded guiding structures such as rectangular and the ridge waveguides and (iii) a Low Temperature Corifed Ceramics multilayer fabrication process. The combination of these technologies is leveraged to design and fabricate array antennas with low-loss beamforming networks and very high-Q ceramic resonator radiating elements. Simulation and measurement results covering the 27–31 GHz frequency band are presented to illustrate the achievable performance.
