原始语种摘要: A compact circular ring antenna with defected ground structure (DGS) has been design for Ultra-Wide Band (UWB) applications. Initially, a circular patch antenna is design by introducing a rectangular DGS structure. Further, slot has been inserted in circular patch to improve the impedance bandwidth. The proposed design covers the frequency range of 2.4-10.4GHz below -10dB. Proposed antenna has design and fabricated on FR-4 substrate having 1.5mm, 4.3 thickness and dielectric constant, respectively. The performance of the designed antenna is analyzing with optimized dimensions in terms of return loss, VSWR, radiation pattern, gain characteristics, group delay and surface current distributions. Further, performance analysis of the proposed antenna has also been compared with existing...
