A New Type of Microstrip Coupler with Complementary Split-Ring Resonator (CSRR)
A new type of microstrip Coupler with Complementary Split-Ring Resonator (CSRR) is proposed. The characteristic impedance of the even mode can be enhanced by etching CSRR structure in the grounded plane of a conventional microstrip double-line coupler. This results in a higher degree of coupling. Based on the analysis of the odd and even modes, a new type of microstrip coupler was designed. The results of simulation and measurement show that the new coupler achieves a high degree of coupling (3 dB coupling) over a wide frequency band (38.1％ relative bandwidth).
