Abstract
Antennas comprise a reflector and first and second arrays of first radiating elements mounted on the reflector. The antenna further comprises a parasitic element including a metal ring, where the metal ring of the parasitic element is arranged between a first radiating element of the first array and a first radiating element of the second array. The antenna can improve the isolation between adjacent arrays, thereby improving the radiation patterns generated by the arrays.
