[IEEE 2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting - Atlanta, GA, USA (2019.7.7-2019.7.12)] 2019 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting - Grounded Coplanar Waveguide-Fed Millimeter Wave Volumetric Pyramidal Horn on LTCC

摘要： There is a strong interest to implement antenna-in-package (AiP) systems for a variety of applications such as imaging, beamforming, integrated transceivers, and radars. Substrate integrated horn antennas are valuable AiP candidates due to their small form factor, ease of integration, and high gain. Alternatively, a volumetric packaging approach can significantly reduce the antenna’s form factor and enhance the gain. For the first time, in this paper, we present a 94 GHz low temperature cofired ceramic (LTCC) integrated volumetric pyramidal horn antenna. Using a vertical LTCC approach, a GCPW-fed single horn antenna was designed. Results show that the antenna operates from 91.6 GHz to 95.6 GHz for S11 <10 dB, with a realized gain of 8.7 dBi.
