Wideband Slotted Planar Antenna with Defected Ground Structure
This paper introduces a novel design of a multi-band microstrip antenna based on slot loading technique.Incorporating up to seven slots in the conventional microstrip rectangular patch antenna maintains the multi-band performance and a thin profile characteristic of the antenna.The geometrical configuration of the slots can be chosen according to a certain application to yield the required operational frequencies with wide bandwidths.The frequency range 2-8 GHz which is appropriate for many applications such as WLAN,Mobile WiMAX,and WCDMA is considered.The effect of the structure of the ground plane on the antenna performance is studied by mounting the proposed antenna structure either on a conventional perfect electrical conductor(PEC)ground plane or on a defected ground structure(DGS)ground plane.The antenna is fabricated.The measured data of the return loss versus frequency show very good agreement with the simulated results.The results show that the proposed antenna with DGS ground plane achieves wider bandwidth and high gain than that of conventional PEC ground plane.
