摘要：
A novel miniature high selectivity filter designed using a metamaterial resonator based on four grounded spirals (ForeS) is presented. This enables extreme size reduction together with high out-of-band rejection and low insertion loss. A fabricated third-order filter has overall dimensions of lambda(g)/4 by lambda(g)/15, a 3 dB bandwidth of 3.7% at 1.63 GHz, insertion loss of 23 dB, attenuation greater than 75 dB in the lower stopband and greater than 40 dB up to 2.6 times the centre frequency.
