研究目的
Investigating the design and performance of a high-selectivity dual-polarization filtering antenna with metamaterial for 5G application.
研究成果
The designed high-selectivity dual-polarization filtering antenna with metamaterial demonstrates superior performance in terms of roll-off rate and out-of-band rejection, making it suitable for 5G anti-interference wireless terminal communication systems. The study confirms the effectiveness of integrating metamaterial layers to enhance antenna selectivity and filtering characteristics.
研究不足
The study acknowledges the inevitable measurement errors and the trade-off between the gain at low pass band and the enhanced roll-off rate at high pass band edge due to metamaterial loss.
