英文摘要: A newly asymmetrical spurline structure is presented in this article. Its dual-bandgap characteristics art reported and call be adjusted by changing the length difference between spurlines. Then, a simple circuit model is set up for the spurline structure by using two LCR-resonators and the circuit parameters call be extracted front EM simulations. Moreover, a Wilkinson power divider using the proposed spurlines was designed, fabricated, and measured. Experimental results verify that 27-dB suppression for the second harmonic and 30-dB suppression for the third harmonic are obtained, respectively. In addition, the reflection coefficients are -3.5 dB +/- 0.3 dB (-3 dB for ideal case) below 3.8 GHZ and -3.7 dB at the operating frequency 3.12 GHz. (c) 2008 Wiley Periodicals, Inc.
