Design of a Bandpass Filter Using Parallel Coupled Stepped Impedance Resonator Using the Novel Method of Lines
The main objective of this paper is to design and analyze a filter at 4 GHz,with bandwidth of 200MHz to be used in a portable transceiver system.The filter should have short length and suppression of first harmonic to obtain a wide stopband.The analysis is applied using the novel method of line.Also,this analysis is developed by nonequidistant discretization to reduce the discretization window.Based on this algorithm,bandpass filters using parallel coupled stepped impedance resonators are designed and examined.Also,a bandpass filter using the conventional parallel coupled line was designed and examined by this algorithm,to be our reference for comparison.The bandpass filter using parallel coupled stepped impedance resonator was fabricated using thin film technology and photolithographic technique,where good agreement is found between the numerical and experimental results.The filter length is reduced by about 23%compared to the conventional one and the first harmonic was attenuated by about 22 dB.
