Effect of thickness of substrate on antenna design for advance communication

Abstract

Present paper is fully dedicated for antenna design for advance communication systems. Substrate thickness has been taken as key role for antenna performance characteristics. Rectangular microstrip antenna with fractal over the patch is considered with height of substrate, and compared with thickness for improve return loss and efficiency. Results obtained with the help of commercial software CST microwave studio for frequency range 2–4 GHz. Improvement in return loss is found −46.8 dB and VSWR 1.005 dB as compared to −45.7 dB and 1.008 dB.
