Summary:
For the past few years, the research works within the area of electromagnetic band gap have been rapidly increased especially in the area of antenna design. Various shapes, structures and dimensions have been analyzed using different numerical methods [1] and a lot of novel applications have been achieved [2]. Some of the EBG properties that had been determined were band gap [3], stop band and band pass frequency [4]. One of the properties that make EBG structure unique is that the structure providing different phase reflection varies with frequency [5]. At certain frequency where the "band gaps" occur, the EBG structure provides in phase reflection which is good for artificial ground plane for low profile antenna design [5-6]. Other than in phase reflection, EBG structures provide stop band at certain frequency ranges where it is also called a forbidden frequency range [7]. In the forbidden frequency range, it will not support any propagation of waves within the substrate for all polarization state and all angles. Hence, this structure is suitable for planar antenna application for reducing the effect of surface waves and mutual coupling which is normally degrades the antenna performances [8].
