Their equivalent circuit are also derived. This structure can suppress both of 2.3-2.4 GHz and 5~6 GHz bands at the same time, with suppression level -30 dB and -50 dB, respectively. Secondly, utilize the dispersion diagram to optimize the design parameters and estimate the stopband. Finally, a simple method of suppression contour map is proposed to analyze position optimization of the structures. Six 2 × 2 combinations can suppress the noise propagation in two stopbands by 5-10 dB, and measurements are carried out by using VNA and SQA. Both simulation and experimental results are used to validate the method. Besides, the design rule and the theory are also discussed in detail. Ruey-Beei Wu 吳瑞北 2018 學位論文 ; thesis 73 zh-TW |
