Abstract
The satellite communications industry, following the trends seen in personal communications systems, is pursuing the development of smaller and more capable communication terminals. Several antenna technologies and architectures have been studied for a fixed-beam portable communications terminal operating at high frequencies, e.g. 20GHz (receive) and 30GHz (transmit), and capable of providing multiple data links (data, voice, video). However, additional work is required to develop a modular "brick" type of architecture for this applications. The report investigates two aspects of the problem: a modular antenna array configuration, and a suitable feeding scheme involving perpendicular interconnection that is essential to the design of the brick architecture. An antenna array patterns program was developed within the Matlab environment. This versatile tool can be used to predict planar array radiation patterns for design and general illustration purposes. The program can evaluate, display and analyze two- and three-dimensional radiation patterns, and it can easily be modified to suit specific user requirements. An array configuration suitable for fixed-beam portable satellite applications at 30GHz was developed using this program. TRUNCATED
