摘要
A multi-band radiating array includes a planar reflector, first radiating elements defining a first column on the planar reflector, second radiating elements defining a second column on the planar reflector alongside the first column, and third radiating elements interspersed between the second radiating elements in the second column. The first radiating elements have a first operating frequency range, the second radiating elements have a second operating frequency range that is lower than the first operating frequency range, and the third radiating elements have a third, narrowband operating frequency range that is higher than the second operating frequency range but lower than the first operating frequency range. Respective capacitors are coupled between elongated arm segments and an elongated stalk of the third radiating elements, and a common mode resonance of the third radiating elements is present in a lower frequency range than the second operating frequency range.
