Abstract

As the size of the antenna often has a significant influence on overall dimensions of the wireless system, its reduction in size becomes a significant challenge. The objective of this chapter is to present new contributions made for reducing the size of the antenna array while maintaining excellent performance. An overview of the antenna array is introduced. Then, two designed and fabricated antenna arrays with compact size and good performances are exposed. The first microstrip patch antenna array is miniaturized using a novel shape of defected ground structure (DGS) etched in the ground plane of each radiating element of the antenna array. While the second one is two antenna arrays which are separated by two magnetic walls of a planar compact electromagnetic band gap (EBG) structure, with the aim to miniature and to reduce the mutual coupling between them, keeping both the antenna arrays separation smaller than 0.6λ5.8GHz. A full-wave electromagnetic analysis had achieved to evaluate the electrical performances of the proposed structures by using HFSS and CST-MWS.
