研究目的
To design a wideband, low-loss antenna array for 5G mmW applications utilizing metasurface and bandgap structure.
研究成果
The proposed 60 GHz 1×2 wideband low-loss antenna array demonstrates satisfactory performances, confirming its wideband property and potential for subsequent larger aperture antenna arrays.
研究不足
The lower resonating frequencies of the measured results have a 800 MHz frequency shifting compared to simulations, caused by fabrication errors.
1:Experimental Design and Method Selection:
The design involves a metasurface excited by a 1×2 slot array coupled to a gap waveguide (GWG) to enhance matching bandwidth and gain. Quasi-TM30 mode is introduced by 3×3 subwavelength patch matrices. A low-cost GWG divider is optimized for low transmission loss.
