Development in Compact EBG and FSS Structures for Antenna Applications

Miniaturization of planar microwave components and antennas has become important for applications where physical space is constrained. Modern wireless communication terminals require small planar microwave elements integrated into compact and light-weight systems. As we concern about small elements in an integrated system the design of the antenna is a significant issue of any wireless system. Antenna designs play a significant role in the development of modern wireless communication devices. However the design of conventional antennas encounters severe practical limitations such as narrow bandwidth and poor radiation characteristics. Thus many design efforts on antenna designs have been focused on enhancing bandwidth and shaping of the radiation pattern. One exciting breakthrough is the use of electromagnetic band gap structures (EBG) technology in antenna designs. A great research effort on EBG structures to be compatible with antenna designs over a wide range of applications have attracted in this book.
