Abstract
This paper presents the design of compact slotted rectangular microstrip patch antenna for operates 5 GHz. The proposed antenna is designed on RT duroid substrate with dielectric constant of 2.2 and fed with 50 ohms microstrip line. Further DGS (Defected Ground Structure) technique is used to increase the gain of the antenna. Bandwidth is enhancing by introducing the slot in the rectangular patch antenna. The characteristics of the proposed antenna have been studied with the help of HFSS (High Frequency Structure Simulator) software. HFSS is a high performance full wave electromagnetic (EM) field simulator. Ansoft HFSS employs the Finite Element Method (FEM). The design targets the frequency band (5.180 – 5.825 GHz) being used in various wireless communication systems, such as satellite communication, radio altimeters etc. The final antenna produced 720MHz bandwidth,1.11 VSWR and 7.27dB gain at frequency 5.39 GHz. General Terms In this paper slotting has to be done to enhance the bandwidth.
