Abstract :

In this paper , a simple, multiband square molded microstrip patch antenna based on fractal geometry for satellite application has been presented. The proposed antenna comprises of three iterations. The antenna has measurements 24x24sq.mm. The composite material of FR4 as a substrate of relative permittivity of ɛr=4.3 and 1.6mm thickness. The antenna is feed with microstrip feed line. The proposed antenna work in X band (8 to 12GHz) and in lower Ku band (12 to 14GHz). It has resonance frequency of 10.1GHz which is appropriate for satellite applications. By utilizing fractal geometry the proposed antenna emanates on various frequencies like 8.5GHz, 10.1GHz, 12GHz, and 13.4GHz. The reenactment results demonstrate the return loss, radiation pattern, VSWR, directivity and gain of the antenna. The software used for simulation is CST microwave studio2017 (student version).
