Study of Microstrip Antenna Using VariousTypes of EBG Cells

[摘要] In this paper the study is done by loading the various types of Electromagnetic Band Gap (EBG) cells on the ground plane of the Microstrip antenna (MSA). The antenna1 gives a virtual size reduction of 59.10% and gives a multi bands and operates in the frequency range of 1 to 15 GHz and gives the enhanced bandwidth of 33.35%. The antenna2 gives a maximum virtual size reduction of 80.3% and gives a multi bands and operates in the frequency range of 2 to 14 GHz and gives the enhanced bandwidth of 61.85%. The proposed antenna is simple in its structure with low cost substrate material. The proposed antenna may find application in microwave communication systems.
