In this paper, Hairpin Bandpass Filter (HPBF) is designed, simulated and fabricated at two 5G low-frequency
bands: 3.7 GHz- 4.2 GHz and 5.975 GHz-7.125 GHz. This filter will be a part of our 5G narrowband/ Ultra Wide
Band (UWB) reconfigurable antenna project that plays a significant role in the recent wireless networks, such as
Cognitive Radios (CRs). Through the two frequency bands, the filter resulted in good matching and transmission
responses with enhanced bandwidth. The measured reflection coefficient of the proposed HBPF, S11 is <-10 dB
and <-11.66 dB through 3.45 GHz – 4.25 GHz and 5.62 GHz – 7.6 GHz, respectively. However, the transmission
coefficient, S12 is around-1.5 dB and – 1.17 dB at the center frequencies FC = 3.75 GHz and 6.61 GHz,
respectively. In this paper, the High-Frequency Structure Simulator (HFSS) software is used to carry out the
simulation. The full-wave simulation results are validated with the hardware measurements.
