Abstract


In this paper, a rectangular microstrip patch antenna with a defected ground structure is proposed.  Bandwidth is improved with a good impedance matching which is suitable to use in various applications. Inverted-F Shaped defected ground structure (DGS) is proposed in this paper to achieve this enhancement. With the proposed design method, using a simple single layer structure, an enhanced bandwidth of 650 MHz ranging from 8.07 GHz to 8.72 GHz is achieved for C and X bands respectively. Besides that, compares the performance of the proposed antenna over a traditional rectangular patch antenna. The microstrip patch antenna is designed and simulated using the high frequency simulation software FEKO.


Keywords
