    Abstract: Base station antennas include a first array of radiating elements that is coupled to a first RF port through a first feed network, a second array of radiating elements that is coupled to a second RF port through a second feed network, and first and second circuit elements. The first circuit element has a first port coupled to the first feed network, a second port coupled to a first port of the second circuit element and a third port coupled to a first radiating element of the first array of radiating elements. The second circuit element has a second port coupled to a first radiating element of the second array of radiating elements and a third port coupled to the second feed network.

    Abstract: A dipole antenna includes a planar reflector and a radiating element. The radiating element includes first and second pairs of dipoles on a surface of the planar reflector. The first and second pairs of dipoles respectively include arm segments arranged around a central region in a box dipole arrangement. The arm segments may be printed circuit board portions having respective metal segments and respective inductor-capacitor circuits thereon. The inductor-capacitor circuits define a filter aligned to a frequency range higher than an operating frequency range of the first and second pairs of dipoles.

    Abstract: A base station antenna includes first and second arrays that include respective pluralities of first and second radiating elements arranged along the longitudinal direction of the base station antenna, the second array transversely adjacent the first array. A longitudinal position of each second radiating element is staggered from that of the corresponding first radiating element. The first array comprises first and second sub-arrays, each of which comprises one or a plurality of adjacent first radiating elements. A phase center of the combination of the first and second subarrays is basically aligned with a sub-phase center of the second array.

    Abstract: A base station antenna comprises a plurality of columns of first radiating elements configured for operating in a first operational frequency band, each column of first radiating elements comprising a plurality of first radiating elements arranged in a longitudinal direction and an isolation wall positioned between adjacent columns of first radiating elements and extending in the longitudinal direction. The isolation wall comprises a frequency selective surface configured such that electromagnetic waves within the first operational frequency band are substantially blocked by the isolation wall.
