Study of Reconfigurable Multiband Micro strip patch antenna for wireless communication

Abstract: Now a days, Microstrip Patch antennas have become a rapidly growing area of research. Their applications are limitless, because of their light weight, compact size, and ease of manufacturing. One limitation is their inherently narrow bandwidth. Hence the main objective is on to increase the bandwidth of the antenna. Design and analysis of Compact Multiband Microstrip Patch Antennas and a circularly polarized microstrip antenna for many kind of wireless communication applications are studied and presented. The multiband antenna posses 14-dB around the GSM 900 band of operation and greater than 8-dB return loss with bandwidths enough to cover the intended higher operating bands. As the proposed antenna can achieve such wide operating bandwidth with relatively low profile, it is very suitable for multi-band mobile communication handsets. The antenna is suitable for use in hand-held or other mobile devices. The new antenna can be used for several applications, especially in the GSM domain, and for Wi-Fi, Bluetooth, and several other applications, as detailed in this paper.
