Triple Band PIFA Antenna Using The DGS Method
Abstract: In this paper, a new design of a triple band Planner Inverted –F Antenna (PIFA) with DGS, for mobile and wireless communication systems is presented. The PIFA antenna consists of ground plate, patch antenna, feeding port and shorting plate connected to the ground plate. The designed antenna has been simulated with the help of the CST (computer Simulation Technology) software microwave studio 2010. The simulated results calculated for the resonant …

Bandwidth Enhancement of MPA using DGS
Abstract: In this paper, the authors proposed an MPA with DGS to enhance its parameters and mainly bandwidth of the antenna. To achieve a very important bandwidth enhancement the authors proposed a rectangular shaped symmetrical DGS in the ground plane. This DGS on the ground plane increases the fringing field which reluctantly increases the parasitic capacitance. This increases the coupling between patch and ground which make the bandwidth to increase from …

Design of Lowpass Filter with Improved Roll Off Factor using Coin Shape Fractal DGS
Abstract: This paper presents the design of lowpass planar filter with improved roll of factor. To improve the performance figures of filter such as return loss, roll off factor, compactness, etc. coin shape fractal defected ground structure (DGS) has been embedded in the ground plane of the filter. The proposed filter gives improvement of roll off factor about 5 times as compared to traditional filter design technique. Laboratory prototypes of all …
