In the proposed work, a multiband Sierpinski arrowhead fractal antenna with 3 × 3 Circular Split Ring Resonator (CSRR) Array integrated ground for various wireless applications is presented. The implementation of third-order Sierpinski arrowhead fractal structure makes the prototype occurs in a compact cross-sectional area with multiband resonances. The complete dimension of the antenna is 60 × 70 × 1.6 mm3 which is made using a FR-4 dielectric material sandwiched by Sierpinski arrowhead radiator and 3 × 3 CSRR Array integrated ground. The CSRR generates magnetic susceptibility media to establish a robust magnetic connection with an applied electromagnetic field. The proposed fractal printed monopole antenna design exhibits resonances from 4.54 to 4.83 GHz, 7.14 to 7.96 GHz, and 11.71 to 12.26 GHz coupled with an average gain of 5.1 dB. The fabricated prototype obtains a strong alignment during both testing and measurement processes, experimented using a Microwave analyzer. The antenna resonates effectively at 5G (n79) band and Satellite Communication and RADAR applications.

摘要

In the proposed work, a multiband Sierpinski arrowhead fractal antenna with 3 × 3 Circular Split Ring Resonator (CSRR) Array integrated ground for various wireless applications is presented. The implementation of third-order Sierpinski arrowhead fractal structure makes the prototype occurs in a compact cross-sectional area with multiband resonances. The complete dimension of the antenna is 60 × 70 × 1.6 mm3 which is made using a FR-4 dielectric material sandwiched by Sierpinski arrowhead radiator and 3 × 3 CSRR Array integrated ground. The CSRR generates magnetic susceptibility media to establish a robust magnetic connection with an applied electromagnetic field. The proposed fractal printed monopole antenna design exhibits resonances from 4.54 to 4.83 GHz, 7.14 to 7.96 GHz, and 11.71 to 12.26 GHz coupled with an average gain of 5.1 dB. The fabricated prototype obtains a strong alignment during both testing and measurement processes, experimented using a Microwave analyzer. The antenna resonates effectively at 5G (n79) band and Satellite Communication and RADAR applications.
