Abstract
This paper presents a fractal, triangular-shaped, multiband, satellite-application antenna created using glass-microfiber-reinforced PTFE material. Different substrate materials are used to determine the performance and characteristics of the proposed antenna design. The radiating patch of the antenna consists of two triangular shapes with two triangular-shaped slots that are connected via a microstrip line and a small slit, while the heptagon ground-plane shape consists of a heptagon slot. The antenna made from the proposed material has attained bandwidths of 45 MHz, 110 MHz, 150 MHz and 230 MHz at centre frequencies of 5.67 GHz, 6.52 GHz, 7.66 GHz and 8.88 GHz, respectively. Experiments have been performed to test the design of the proposed antenna. In addition, the effects of different geometrical parameters on the performance of the antenna have been analysed using a 3D EM solver HFSS (High Frequency Structure Simulator). The physical antenna dimensions are 30 mm x 40 mm x 1.575 mm.
