Abstract
This document presents the investigation of a novel end-fire antenna implemented in laminated material. This study is related to the development of a phased array for the AEHF Military Satellite Communication Systems. This work includes theoretical analysis, computation of the developed models and measurement of the realised prototypes at 20.7GHz. The antenna element consists of a radiating rectangular waveguide. As a laminated dielectric material, like LTCC material, is supporting the antenna, the vertical walls need to be formed with vias of specific pitch. An effective coaxial-to-waveguide transition has also been developed to feed the radiating element. The results show that this laminated waveguide can be used as an integrated radiating element in the AEHF band for military satellite communications. A five-element array has also been prototyped. Although the results show low mutual coupling between the elements, additional work needs to be carried out to improve the array radiation characteristics.
