Microstrip Patch Antenna with BiNbO4(V2O5) Substrate and Copper Periodic Structures

Abstract

The use of high permittivity materials on substrates of a microstrip antenna was developed with Bismuth Niobate ceramic doped with vanadium Oxide (BiNbO 4 (V 2 O 5 )) and compared with an antenna of silicon dioxide substrate (SiO 2 ) using Ansys software HFSS and CST Studio. The ceramic antenna has -20 dB at 3.5 GHz and the silicon dioxide antenna -24.7 dB of reflection coefficient. The bandwidth values are 80 MHz for the bismuth ceramic antenna and 100 MHz for the silica antenna. The results demonstrate that the proposed BiNbO 4 antenna has great advantage compared to those mentioned in terms of volume reduction, presenting results similar to those antennas with higher volume. In addition, we use copper periodic structures (EBG) in order to increase the gain in associated with the use of BiNbO 4 with addition of V 2 O 5 on the antenna substrate leading to a reduction in the total volume. Therefore, the proposed Bismuth Niobate antenna proves to be an excellent alternative for 5G technology and microwave S band (2-4 GHz) devices, highlighting the mentioned advantages.

Silicone rubber‐nanoceramic composites for 5G antenna substrates

“…With the merits of high data rates, increased bandwidth capacity, high reliability, and low latency, the Fifth Generation Mobile Communications System (5G) has emerged as an alternative to Fourth Generation (4G) technology [1][2][3][4]. Two frequency bands can be used in the 5G network: the millimetre wave range and sub-6 GHz (1-6 GHz).…”
