In this article a simple and small size wideband square patch antenna has been examined for band notch characteristics. In order to broadening the band width of the simple patch antenna, the role of partial ground has been critically studied and analyzed. The presented methodology reveals that the implementation of meander line fractal shaped defected ground structure not only augment the band width of the antenna but also provide a notched band at 12.14 GHz required to reject the interference for existing wireless communication. A prototype of the proposed antenna has been fabricated to validate the simulated results. The measured and simulated results are in good agreement.
