DESIGN AND ANALYSIS OF MICRO STRIP PATCH ANTENNA

Abstract

Wireless technology in the field of communication systems is very vast research area of research at very high priority at present age. In wireless communication system fabrication of antennas plays an important role. Antenna fabrication is the main cause to select a project focusing on this field. A revolutionary change has been noted over the interest of researchers in the field of antenna design in the last few decades. Interest of researchers includes the commercial/personal communication. In our day to day life users wish to have a light weight and small handset, and this can be possible by proper designing the antennas. Due to the development of VLSI/ULSI techniques the researchers are able to reduce the size and power hungry of the devices to a greater extent. Antenna become the front and back end of the wireless communication system. The potential application of Monopole Antenna for the wireless and personal commutation is the hot topic of interest of the researchers around the globe. The present day demands wide band, miniature antennas with other features. The choice of MSA for communication is basic demand of the present-day communication. The following thesis consists of a monopole micro-strip antenna. The dielectric used in the designing of this monopole antenna is FR4. The top portion of the antenna consisting of a patch having rectangular slot, micro-strip line and bottom part consists of a partial ground plane with a semi elliptical notch. The overall size of dielectric is 30*30*1.5. The fractional bandwidth of this structure is 3.41 – above 25 GHz. The bandwidth enhancement is due to cutting various types of slots in the patch and ground plane.
