High-Order Characteristic Modes Suppression for Cross-Band Decoupling in Shared-Aperture Antenna Array
文献摘要：
In dual-band shared-aperture base sta-tion antennas,the secondary radiation(SR)field caused by cross-band couplings always leads to radiation pattern distortion.In this work,the SR field caused by the coup-ling is attributed to the excitation of the target high-order modes from the perspective of the characteristic mode.To effectively suppress the target modes,L-shaped slots are proposed to load the arms of the radiator and altering the current paths.As compared with convention-al dipoles without L-shaped slots,the proposed antenna generates less SR field.Therefore,the radiation pattern of the high-band antennas keeps stable in a dual-band shared-aperture antenna array environment.Prototype of a dual-band antenna array consisting of the proposed low-band(LB)antenna and a 4×4 high-band(HB)antenna array is fabricated.Simulated and measured results show that the designed dual-band array operates at both 0.74-0.82 GHz and 3.30-3.80 GHz.The experimental results verify that the cross-band decoupling has been achieved with the high-order mode suppression.
