摘要：
An improved compact microstrip resonance cell (CMRC) structure is presented. Good lowpass performance and wide stopband characteristics can be achieved with a simple single resonant cell; four transmission zeros are introduced into the stopband and thus out-of-band rejection is significantly improved. Measured results of the fabricated prototype show that the insertion loss is less than 0.1 dB in the whole passband, and stopband bandwidth better than -10 dB is obtained from 2.9 to 15.9 GHz, which is an improvement of 138.3% from a conventional CMRC.
