Design of Multilayer High Impedance Surface for Antenna Applications
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2013, Vol 2, Issue 4
Abstract
In the recent years High Impedance structures are drawing lot of interest in electromagnetic and antenna community. Due to compact sizes of electronic devices, required radiating element to be placed closed vicinity to electronic and biological systems hence designed antenna should have maximum radiated gain, with minimum near filed coupling with environment. This is achievable with periodic electromagnetic structures. By the Engineered electromagnetic surface textures, the properties of the metal surface are altered to perform required functions, such as change of surface impedance, to manipulate the propagation of surface waves or to control the reflection of phase. My present paper concentrating on two dimensional HIS, Multi layered mushroom type metal protrusions. They are analyzed as resonant LC circuits, These materials provide high impedance boundary conditions for both polarizations and for all propagation directions
