Abstract: In this paper, a rectangular microstrip patch antenna for multiband operation is designed and simulated. The proposed geometry of antenna covers three frequency bands and can be used for different wireless applications. The designed antenna has simple shape of rectangular patch with a co-axial feed. The performance parameters for proposed rectangular multislot antenna such as return loss, gain, directivity, bandwidth, VSWR are studied. The proposed antenna shows maximum gain up to 6.69dBi, bandwidth above 108MHz, and maximum directivity of 10.53dBi. IE3D (Integral Equation in Three Dimensions) software has been used for design and simulation of proposed antennas.
