Abstract :
A Microstrip triple-band band pass filter for GSM 900, GPS - L1 band and 2.4 GHz -WLAN applications is designed and simulated using Agilent® ADS software. Three transmission zeros are inserted at frequencies of 1.31 GHz, 1.96 GHz and 2.89 GHz, to achieve good out of band rejection. Insertion loss of 3.88 dB, 3.78 dB and 4.8 dB at central frequencies of 925 MHz, 1.575 GHz and 2.4475 GHz are observed for the designed filter, measured after the fabrication.
