Abstract

The paper presents the design of Interdigital Band Pass Filter (IBPF) for WLAN applications at center frequency 2.45GHz. It was designed using a 3D EM simulation tool and fabricated on substrate Ferro A6S by using in-house process of Low Temperature Co-fired Ceramic (LTCC) technology. Simulated and measured results were presented. The pass band insertion loss of the filter was measured to be -1.66dB at 2.45GHz within the specification, S21 <; -3dB. The return loss was measured at -15.57dB which better than specification, S11 >; -10dB.
