Abstract: Here in this paper a triple band microstrip antenna is proposed. The designed antenna is of compact structure with dimensions 96mm x 27mm x 1.6mm including ground plane which is fabricated using Fr-4 substrate with dielectric constant of 4.6.This antenna has three resonant frequencies which are working at 6.6GHz with bandwidth of 1.1 GHz second band working at 8.3 GHz with bandwidth of 200MHz. and third operating frequency is 9.4GHz with bandwidth of 750MHz. All the band obtained here are providing large bandwidth which have wide range of applications. The other antenna parameters like return loss, directivity, gain, VSWR and current distribution are mentioned in this paper. The main purpose of this antenna was to provide a single antenna for multiple applications and with improved bandwidth for transferring large amount of data. The designed antenna is suitable for industrial applications also as because of its compact structure and its wide range of applications like radar, communication satellites, radiolocation, navigation air traffic control etc.
