Compact Microstrip Patch Antenna with Parasitic Loading for X & Ku Band Applications
Microstrip patch antennas are becoming popular day by day because of the various advantage offered by them such as low cost,less weight,low profile and ease of fabrication 1.Popularity of patch antenna can be known from the fact that they found their application in various fields like aircraft,space technology 2,3,mobile communication,biomedical,broadcasting etc..However narrow bandwidth of patch antenna is one of the major limitation,that researcher around the world have been trying to overcome.Many techniques have been suggested in the past in order to overcome this problem 4.One such technique is employed in this paper in which parasitic elements are used along with driven patch excited with the help of coax feed for X & Ku band.An equivalent circuit of the proposed antenna is also developed and analyzed.The antenna is designed on FR4 substrate with permittivity 4.4 and having dimension of ground plane 17 × 19mm2.The patch has a dimension of 6 × 6mm2 which is loaded with parasitic elements.The proposed antenna is able to achieve impedance bandwidth of 1.8 GHz from 10.8 GHz to 12.6 GHz thus,covering Ku band as well and has a maximum gain of 3.9 dBi.Comparison between simulated and fabricated results would be presented.The return loss,electric field distribution,radiation pattern of the proposed antenna is presented in this paper.All simulations are done by using HFSS software.
