Millimeter-wave Substrate Integrated Waveguide Band-pass Filter Based Filtering Magneto Electric Dipole Antenna

초록

This study proposes an integrated narrowband antenna system by combining SIW BPF technology with an ME dipole antenna, centered at the core frequency of 58 GHz within the range of 56.5 GHz to 59.2 GHz. The size of the combined structure is 4mm × 14mm. One of the components, the SIW BPF, has been designed with optimized parameters and resonates at 59 GHz with a fractional bandwidth (FBW) 4.23% through parametric analysis. The ME antenna covers the range of 54.56 GHz to 74.67 GHz using single feed line. The proposed structure demonstrates a downward phase shift of 1.25 GHz compared to the SIW BPF's range and achieved return loss of -14dB. © 2023 IEEE.
