Design and Simulation of Multi Band Microstrip Antenna for X Band and Ku Band Applications Using Nano Barium Hexa-Ferrite,BaFe_(12)O_(19)

摘要

A new dielectric patch antenna prototype for multiband operating from 8 GHz to 18.58 GHz is presented in this paper. This antenna is designed with nanocrystalline barium hexaferrite, BaFe_(12)O_(19) material sandwiched between two FR4 substrates which is suitable for incorporation with radio frequency circuitry. Return loss improvement has achieved by the antenna with BaFe_(12)O_(19) substrate. Further by optimizing the thickness of BaFe_(12)O_(19) dielectric layer return loss of the antenna has significantly improved. The BaFe_(12)O_(19) antenna had an overall increase in gain, directivity, bandwidth and radiation efficiency. Due to the remarkable performance of the BaFe_(12)O_(19) antenna, it could be considered as a good candidate for dielectric substrate in satellite communication applications. The antenna structures were simulated by using the momentum simulation method of the software Advanced Design System-2011.10.
