Study and Analysis of Hexa Shape Patch Antenna on L-Band and S-Band

In this paper, we designed a hexa shape patch antenna for L-band & S-band application. After designing the antenna on 1.8GHz (L-band) and 2.5GHz (S-band) frequency, we study and analysed the results for both bands using ie3d software. For both the bands, we uses the same dielectric substrate 4.2, loss tangent .0012 and having the same substrate height 2mm. The patch and ground plane dimension’s are different for both the bands. The designed antenna on 1.8GHz (L-band) frequency showing the bandwidth 22.9% having return loss -43 dB while the designed antenna on 2.5GHz (S-band) frequency showing the bandwidth 31.9% having return loss -57 dB. All the other respective results i.e, VSWR, gain, directivity, efficiency and 3D-radiation pattern for both the bands are shown by the help of ie3d software.
