Design of octagon shape microstrip
patch antenna for multiband application
Vishant Kumar Chaudhary
In this work three rectangular microstrip patch antenna is presented on glass epoxy FR4 substrate having thickness of 1.6 mm. In these three antennas one is simple rectangular patch antenna and the other two are slotted patch design in the shape of octagon. Probe feed technique is used in all the designs. The multiband behaviour is analyzed using two slotted forms of the designed patch antennas. The proposed antenna covers multiband frequencies in the range from 1.6 to 5.9 GHz. It is simulated using IE3D simulator. Electrical parameters of the antenna like return loss; radiation pattern, directivity & VSWR exc. are investigated. The relationship between geometric sizes of the patch and the electrical parameter speciûcations of the antenna is researched.
