DESIGN AND ANALYSIS OF SWASTIK SLOT LOADED MICROSTRIP ANTENNA AT FR4 LOSSY SUBSTRATE ON L - BAND

This paper presents a novel design of a Swastik shape microstrip antenna with compact nature and the study of various antenna parameters. The antenna is fed by coaxial probe feeding technique. The proposed microstrip antenna is designed and simulated in CSTsimulation software. Design antenna at 1.7GHz (L - band) frequency, we study and investigate the results using CST software. We use the same dielectric substrate 4.2, loss tangent.02 and having the same substrate hei ght 1.6mm. The antenna size is very compact (52.29 mm × 67.74 mm × 1.6mm) and covers 1.7 GHz to 2.6 GHz The designed antenna on 1.7GHz (L - band) frequency showing the bandwidth 21.7% an having return loss - 21.783 dB. All the other respective results, i.e., VSWR, gain, directivity and power pattern of both the bands are shown with the help of CST software.
