Simulation and fabrication of hexagonal multiband fractal antenna

Simulation and fabrication of hexagonal multiband fractal antenna / Wan Nasrul Hakim Wan Ismail Nasiruddin
Di dalam projek ini, sebuah antena tampalan berbentuk heksagon dengan slot-L yang diubah suai bertujuan untuk pengunaan applikasi multiband. Substrat FR-4 dan Rogers 4003C telah digunakan dengan pemalar dielektrik 4.5 dan 3.65. Slot-L yang diubah suai telah disusun di atas tampalan untuk memberikan kesan resonator dan telah digunakan untuk menjana pelbagai band didalam antenna. Rekaan ini telah dicadangkan oleh Rajimohan dan Hussien didalam kertas IEEE tahun 2016 [1] dan simulasi dan fabrikasi telah dijalankan untuk membandingkan keputusan penyelidikan yang lepas dengan keputusan simulasi yang baru dengan pengukuran fabrikasi daripada dielektrik daripada bahan yang berbeza yang terdapat didalam pasaran. Hasil simulasi menghasilkan respons multiband pada frekunsi resonans 3.088 GHz, 7.952 GHz, 8.848 GHz dan 10.203 GHz dengan kehilangan pantulan minima -28.975 dB dan VSWR <2 untuk FR-4. Substrat Rogers 4003C menghasilkan keputusan yang disimulasikan bahawa tindak balas pada kekerapan resonans 3.612 GHz, 12.020 GHz dengan kehilangan pantulan minima -29.2176 dB dan VSWR <2. Pengukuran fabrikasi menawarkan respons pada frekuensi resonans 3.310 GHz, 5.560 GHz, 8.050 GHz, 13.393 GHz dengan hasil pantulan minima hasil pada -18.84 dB untuk FR-4 manakala substrat Rogers 4003C memberikan frekunsi resonans 3.580 GHz, 5.830 GHz, 8.830 GHz, 10.240 GHz, 11.560 GHz dengan hasil kehilangan pantulan minima pada 20.72 dB. _______________________________________________________________________________________________________ In this project, a hexagonal patch antenna with modified L-Shaped slots, used for multiband applications is proposed. FR-4 and Rogers 4003C substrate used with a dielectric constant of 4.5 and 3.65. Modified L-shaped slot are is arranged on a patch to give resonator effect and are been used to generate multiple bands in the antenna. The design was proposed by Rajimohan and Hussien in 2016 IEEE paper [1] and simulation and fabrication are made to compare with the previous research result with the new simulated result and fabrication measurement from a different dielectric material that is available in the market. The simulated results yield a multiband respond at the resonance frequency of 3.088 GHz, 7.952 GHz, 8.848 GHz and 10.203 GHz with the minimum reflection loss of -28.975 dB and VSWR < 2 for FR- 4. The Rogers 4003C substrate yield a simulated result that response at the resonance frequency of 3.612 GHz, 12.020 GHz with the minimum reflection loss of -29.2176 dB and VSWR < 2. The fabrication measurement offers response at resonance frequency of 3.310 GHz, 5.560 GHz, 8.050 GHz, 13.393 GHz with the minimum reflection loss result yield at -18.84 dB for FR-4 while Rogers 4003C substrate gives a resonance frequency of 3.580 GHz, 5.830 GHz, 8.830 GHz, 10.240 GHz, 11.560 GHz with the minimum reflection loss yield at 20.72 dB.
