Abstract :
A novel capacitively coupled microstrip resonators with multiple 2-D Hilbert curves embedded in and under the microstrip are presented in this paper. The proposed resonators achieve length reduction of over 84% when compared to the conventional resonators. By using the proposed resonators, a compact bandpass filter is designed to work in the GPS frequency band while exhibiting very high attenuation in the neighbouring 1.8 GHz GSM band.
