A Novel Multiband Microstrip Patch Antenna for Satellite Applications
A novel microstrip fed multiband microstrip antenna for satellite applications in C - band, X - band and Ku – band is intended in this paper. The designed receiving wire is planned on FR4 substrate having dielectric consistent of 4.4, thickness 1.6 mm with measurements of 19 X 17 X 1.6 mm3. An intended triple-band model is investigated by etching the three different shapes of openings on the patch. The patch antenna consists of crossed shape dipole slot, rectangular slot and hexagonal slot for triple operating frequency. The structured antenna covers three frequency groups from 4.8 to 5.05 GHz for C-band, from 9.54 to 10.04 GHz for X-band, and from 16.07 to 17.77 GHz for Ku-band satellite correspondence. The simulated return losses are better than -43 dB at 4.9 GHz, -36 dB at 9.7 GHz, and -32 dB at 16.9 GHz. The outlined patch antenna has gain of 5.37 dBi, 5.5 dBi and 6.52 dBi at 4.9 GHz, 9.7 GHz, and 16.9 GHz respectively and VSWR around 1.05 at desired bands. This antenna is easy to model, little in size and has an appropriate band width. The plan of the model and recreation results is done utilizing CST-Microwave Studio programming. The investigated results counsel that the designed antenna is often used satellite applications.
