Abstract
The intent of this study is to realize efficient wideband DRA using unbiased low permittivity yttrium ion garnet (YIG) with excess Fe2O3. The fabricated YIG resonators with the same dimension but different ɛr are used together to produce wideband stacked YIG resonator antenna (YRA). Three stacked YIG resonators with excess Fe2O3 of 8% (YR8), 14% (YR14), and 17% (YR17) present the best YIG resonator combinations with bandwidth of 24.22%. Findings also indicate broadband radiation pattern throughout the design frequency range. The simulated and measured results are all in agreement. In conclusion, this work offers an improved and efficient YRA using YIG resonator with excess Fe2O3.
