Abstract
This document presents the investigation of an end-fire antenna implemented in a laminated LTCC (Low Temprature Co-fired Ceramic) material. The antenna could be employed in a brick architecture phased array for use in an Advanced Extremely High Frequency (AEHF) Military Satellite Communication terminal. The work includes the design, analysis, fabrication and measurement of antenna prototypes at 44.5 GHz. The radiating element consists of a Yagi-like antenna fed by a microstrip transmission line and buried into the dielectric material. Relatively good agreement between simulated results and measurement were obtained. The results show that this radiating element could be used in an AEHF Communication terminal. Future work will involve the study of its electromagnetic behaviour in an array configuration. As the LTCC material has not previously been characterized up to 45 GHz, a study to extract the electrical properties of the LTCC material was also carried out and is reported in this document.
