Abstract
This paper proposes a novel building block for designing Narrowband Bandpass Hairpin filter on PTFE laminate using the Radial stubs. The proposed circuit block mainly consists of coupled lines, microstrip lines, and the Radial stubs. The process starts with the theoretical design procedure of the filter. Tuning and optimization of the design is achieved using AWR Microwave office tool. Finally, the result of the optimized design is suitably presented for implementation. Insertion loss (IL) less than 5 dB and the Return loss (RL) better than 12 dB is achieved with the 11.65 GHz center frequency. Electro Magnetic (EM) simulation results show good agreement with the linear schematic model results.
