Design, fabrication, and test of a radiating element for a KU-BAND smart antennaud

摘要

Planar phased array antennas have been the focus of much research in recent years as candidates for applications such as satellite communication. Many advantages of this kind of antenna like the ability to steer electrically, its high reliability, and its long-term reduced cost motivate further research in this area.ududMicrostrip antennas are extensively used in array antenna because of their low cost and weight. They also can be easily printed over a dielectric substrate with photolithography techniques.ududThe objective of this thesis is the design and fabrication of a wideband dual polarized patch antenna to be used in an antenna array for the application of satellite communications. This patch is designed to work in the frequency domain from 10.7 GHz to 12.7 GHz. In this project we used Low Temperature Co-Fired Ceramic Technology beside printed circuit board which was never applied before. In addition we proposed a new structure for the patch antenna which increases the bandwidth up to 19%. The proposed patches are fabricated with the material 591 and 9K7 Green Tape and Rogers RT5870. The designs were carried out using the planar electromagnetic field simulator Momentum, part of the Advanced Design System (ADS) of Agilent technologies.
