Abstract
By using the ABCD matrix method, it is concluded that when the conventional microstrip line is between 0-180 degrees,the traditional microstrip lines with high impedance can be replaced by the balance CRLH TL with low impedance. According to the analysis results, and with the design principle of the unequal Wilkinson power divider, a 9:1 unequal power divider operating at 2.4 GHz by using CRLH TL with characteristic impedance of 75Ωinstead of theλ/4 traditional microstrip line with 274Ωwas designed. The test results show that the difference between the insertion loss S31and theS21at the operating frequency is 9.35 dB, and the return loss is less than-20 dB in the range of 2.29-2.5 GHz, while the isolation is less than-20 dB in the range of 2-2.6 GHz.关键词
