In this thesis, to determine the pliant structure of circuits and the position of input and output terminals, we use over couplings, SIR structure, and 2.5D to simulate the afflux and intensity of the electric current by increasing the quantity of couplings methods. In this paper, the central frequency is 900 MHz through the analysis of the ADS electromagnetic simulation software with return loss less than under 10 dB, insertion loss less than 3 dB. Stopped band has 50 dB and a four times band above the inhibitory effect of selective filters of bandpass. All of the designs and manufactures are qualified above the criteria: lowest return loss and highest insertion loss, the nice suppression of harmonic, the suppression of highly broadband, and the highly selective filters of bandpass. Finally, the actual circuit implements on FR4 plate, and simulations and measurements have gotten a good consistence. Chih-Ying Chen Shry-Sann Liao 陳志瀅 廖時三 2013 學位論文 ; thesis 101 zh-TW |
