Star Shaped Penta-Frequency Microstrip Radiating Element Design for X, C Band and Satellite Communication

Multiple slot triangular shaped penta band microstrip antenna with micro strip feed line is proposed with an additional surface parameters of 28.4×25×1.67 millimeters. FR4 is chosen as the dielectric for antenna is which has 4.4 as relative permittivity. The penta-band frequency response is obtained with the help of making triangular slots over the patch. It covers five frequency bands. Based on results, for C-Band application,5.1 to 5.3 GHz and 6.1 to 6.3 GHz obtained. For uplink satellite communication in X-band, 7.1 to 7.3 GHz obtained from results. For X-band applications 8.1 to 8.3 GHz and 10.5 to 10.7 GHz obtained. −;31 dB at 5.2 GHz, −;29 dB at 6.1 GHz, −;17 dB at 7.12 GHz, −;22 dB at 8.2 GHz, and −;28 dB at 10.7 GHz are the return losses. At all working resonant frequencies, the VSWR is less than 2. The results are obtained from simulation using CST software and it is in acceptable agreement with the calculated results.
