Analysis and Design of Multiband Antenna Using Modified Geometry

Abstract

As the digital age grows, the communication techniques increase day by day. The backbone of communication is antenna, for which this area of research is still in demand. In this paper, authors try to design an antenna that can be used with multiple bands. By etching the corners of the rectangular patch, an U-slot is inserted to enhance this gain and two stable bands have been generated. To prove it the transmission line model is developed and analysed. As a result the bands are generated and used for 2.9 GHz and 9.8 GHz respectively. From the result it can be observed that the bandwidth and gain of the proposed antenna is increased.
