Abstract
This paper presents the design and simulation of dual band Key shaped microstrip patch antenna exhibiting wide band operating frequencies for C/X band applications. The proposed antenna is designed using FR4 (flame retardant-4) substrate. The impedance bandwidth at lower band (7.02-8.45GHz) is 18.48% and at upper band (10.83-11.71 GHz) is 7.80%. The line feed technique and defected ground structure (DGS) is used in this design. The performance of the proposed antenna is analyzed in term of bandwidth, gain, return loss, radiation pattern, VSWR, radiation efficiency, group delay and axial ratio. The design is optimized to meet best possible result. The simulation has been performed by using HFSS 13.0 simulation software.
