Combined scheme for mitigating coupling interference in dual-band shared-aperture base station antenna
A dual-band shared-aperture antenna array is presented, involving a combined scheme to suppress mutual coupling interference. The proposed array is comprised of a low-band (LB) antenna, a frequency selective surface (FSS), sixteen high-band (HB) antennas, and a reflector. The LB antenna utilises electromagnetic transparent (ET) characteristics to minimise scattering interference, while the FSS isolates resonance interference and port signal interference. The combined scheme integrates the benefits of both the ET antenna and FSS to suppress mutual coupling interference effectively. A prototype of the proposed antenna was fabricated and measured, operating at 1.7–2.7 GHz and 3.3–3.9 GHz. The simulated and measured results demonstrate stable patterns for both the LB antenna and the HB antennas. The cross-band isolation is higher than 28 dB in the low-band. With these advantages, the antenna array is suitable for base station applications.
