Abstract

A dual band bandpass filter for WLAN and RFID application is presented in this paper. The proposed filter is realized using asymmetric fed intercoupled open loop resonators (OLR) with embedded E-shaped resonators with open stubs. The center frequencies of the passbands are 2. 45 GHz and 6. 8 GHz. The insertion loss at each passband is on average within 2 dB. Four transmission zeros are obtained of each pass band for high selectivity. The stop band attenuation is below 10 dB with the band extending up to 10 GHz. The overall size is 28 mm by 15. 25 mm which brings about considerable miniaturization.
