Abstract
This paper presents a novel miniaturized triple-mode microstrip bandpass filter (BPF) designed using the space-mapping (SM) technique. The filter supports three center frequencies at 1.9 GHz, 2.14 GHz, and 2.45 GHz, corresponding to CDMA, WCDMA, and RFID applications, respectively. The proposed design utilizes an RT/Duroid 5880 substrate with a dielectric constant of 2.21 and a thickness of 20 mil, with the conductor layer on the top and a ground plane on the bottom.
The proposed resonator exhibits high rejection levels in the stopband, low insertion loss within the passband, and an integrated compact structure. The overall size of the designed BPF is 4 mm × 36 mm, demonstrating a considerable reduction in physical dimensions. Experimental results show strong agreement with simulated performance. The compact structure, high Q-factor, and low insertion loss represent the key advantages of this filter compared with previously reported designs.
