Base station antennas having f-style arrays that generate antenna beams having narrowed azimuth beamwidths

A base station antenna, comprising:

• a reflector;
• a first radio frequency (“RF”) port;
• a second RF port;
• a first array of radiating elements mounted to extend forwardly from the reflector, where the radiating elements of the first array form a first F-style array of radiating elements, where each of the radiating elements in the first array is coupled to the first RF port;
• and
• a second array of radiating elements mounted to extend forwardly from the reflector.

A base station antenna, comprising:

• a reflector;
• a first radio frequency (“RF”) port;
• a second RF port;
• a first array of radiating elements that includes a first column of radiating elements and a first additional radiating element, where each of the radiating elements in the first array of radiating elements are coupled to the first RF port;
• and
• a second array of radiating elements mounted to extend forwardly from the reflector;
• wherein some of the radiating elements in the first array of radiating elements each have a first dipole arm that extends at an angle of −45° with respect to a longitudinal axis of the first column of radiating elements and a second dipole arm that extends at an angle of +45° with respect to the longitudinal axis of the first column of radiating elements, and other of the radiating elements in the first array of radiating elements each have a first dipole arm that extends parallel to the longitudinal axis of the first column of radiating elements and a second dipole arm that extends perpendicularly to the longitudinal axis of the first column of radiating elements;
• wherein the second array of radiating elements includes a second column of radiating elements and a second additional radiating element, where each of the radiating elements in the second array of radiating elements are coupled to the second RF port;
• wherein some of the radiating elements in the second array of radiating elements each have a first dipole arm that extends at an angle of −45° with respect to a longitudinal axis of the first column of radiating elements and a second dipole arm that extends at an angle of +45° with respect to the longitudinal axis of the first column of radiating elements, and other of the radiating elements in the second array of radiating elements each have a first dipole arm that extends parallel to the longitudinal axis of the first column of radiating elements and a second dipole arm that extends perpendicularly to the longitudinal axis of the first column of radiating elements;
• and
• wherein the radiating elements of the first array form a first F-style array of radiating elements.
