SIMULATION AND DEVELOPMENT OF MULTIBAND MICROSTRIP ANTENNA

Traditionally each antenna operates at a single or dual frequency bands, where different antenna is needed for different applications. This will cause a limited space and place problem. In order to overcome this problem, multiband antenna can be used where a single antenna can operates at many frequency bands. One technique to construct a multiband antenna is by applying microstrip shape into antenna geometry. a modified Auspicious square patch antenna has been designed. For designing this antenna IE3D software is used which is based on MoM technique. The Auspicious microstrip shape is used for designing the proposed antenna. In decomposition algorithm for rectangular shape is cut down from each side of the square patch antenna which shows the 1st iteration. The side length of square patch microstrip antenna is 30 mm (without iteration) and after iteration ‘indentation’ size is 2mm×8mm and square size is 14 mm. This square patch microstrip antenna has scale factor of 2.
