Abstract

In this paper microstrip patch antennais designed for 2.4 GHz frequency. For the antenna miniaturization andbandwidth improvement H-shaped DGS on microstrip patch antenna (MSA) is used.The design of DGS has been analyzed for different dimensions of H-slot andachieved optimized dimensions. The simulation process has been done throughFinite Element Machine (FEM) based software High Frequency Structure Simulator(HFSS) software. The properties of antenna such as reflection co-efficient,bandwidth and gain are determined and compared with the properties of singleelement square patch antenna. Further proposed antennas performance is studiedfor different size of defect on the same patch antenna. Proposed antenna findsits application in wireless LAN protocols such as Bluetooth, IEEE 802.11 and in2.4 GHz ISM Band.
