Abstract:

This paper introduces a dual-band shared aperture base station array based on the embedded scheme, with mitigated cross-band scattering performance. Through inserting innovative helical filters into low-band (LB) radiators, the adverse impact on high-band (HB) antennas caused by close-placed LB antennas is largely restored, across a wideband of 1.36-2.72 GHz (66.7%). Despite matching difficulties brought by the helical filters, the developed LB antenna achieves successful matching in 0.8-0.96 GHz (17%). This is attributed to the specially designed LC series circuits integrated into the LB baluns. Moreover, the incorporation of helical filters extends current paths and enables a compact aperture size of the LB antennas. This leads to enhanced in-band isolation. Consistency between simulations and measurement results in the fabricated array validates the effectiveness of this design.
